Good day, ladies and gentlemen, and thank you for standing by. Welcome to the Lam Research Corporation December 2013 Quarterly Results Conference Call. [Operator Instructions] I would now like to turn the conference over to Shanye Hudson, Senior Director of Investor Relations. Please go ahead..

Thank you, Katia. Good afternoon, everyone, and welcome to our quarterly conference call. With me today are Martin Anstice, President and Chief Executive Officer; and Doug Bettinger, Executive Vice President and Chief Financial Officer.

During today's call, we will share our outlook on the business environment and review our financial results for the December 2013 quarter and our outlook for the March 2014 quarter. The press release detailing our financial results was distributed over the wire services shortly after 1:00 p.m.

this afternoon and can also be found in the Investor Relations section of the company's website, along with the presentation slides accompanying today's call. Today's presentation and Q&A will include statements about our expectations and beliefs regarding certain future outcomes and including our guidance.

A more thorough list of forward-looking topics that we expect to cover is shown on the slide accompanying my remarks. All statements made that are not historical facts are forward-looking statements based on current information and are subject to risks and uncertainties that may cause actual results to differ materially.

We encourage you to review the risk factors in our disclosures and public filings, including our 10-K and 10-Qs. The company undertakes no obligation to update forward-looking statements. Today's discussion of our financial results will be presented on a non-GAAP financial basis unless otherwise specified.

A detailed reconciliation between GAAP and non-GAAP results can be found in today's earnings press release. This call is scheduled to last until 3:00 p.m. Pacific time. [Operator Instructions] As a reminder, a webcast replay of this call will be available later this afternoon on our website. So with that, I'll turn the call over to you, Martin..

FinFET, 3D NAND, patterning and packaging. In the foundry segments, we saw the pace of 20-nanometer investments accelerate at the end of 2013, signaling a robust commitment in the demand for devices using 20-nanometer technology.

As of today, spending is more heavily concentrated between a couple of customers, with capacity additions and conversion activities plans, primarily for the first half of this year.

In the recent period, the foundry space has arguably grown more competitive, with new entrants challenging the delineation of traditional pure-play foundries and logic manufacturers. For foundries, the race to develop FinFET devices has led to multiple pilot line projects starting in the first half of this year.

We expect those investments to continue through the year with total capacity additions dependent on end-user demand and the pace at which production ramps yield. Taken together, our prior forecast for foundry spending between $13 billion and $14 billion, still seems reasonable for 2014.

Similarly, we maintained our forecast for microprocessor and other logic spending of around $6 billion or relatively flat with 2013 levels. Continuing the 2013 theme embedded in our forecast is the expectation that significant leading-edge logic production capacity can be satisfied through equipment reuse and capacity conversions.

Looking at the memory markets, we continue to see stable pricing conditions and tight supply entering 2014, with customers who continue to exhibit due rigor in evaluating their capital spending decisions.

DRAM manufacturers are accelerating transitions to the mid-2x technology nodes and their broader participation of customers are entering 20-nanometer pilot production.

We forecast this supply growth in the low 30% range, led by mobile device demand, and this is accomplished largely through equipment upgrade, albeit, with capital intensity higher than prior generations.

In the NAND segments, remaining planar capacity additions seem clear and the initial 3D NAND production ramp is progressing largely in accordance with our expectations.

Over time, as the 3D devices move to structures with more layers, our customers appear to anticipate cost and performance benefits that support a broad industry conversion, which underpins their plans this year. We currently project between 80,000 and 100,000 wafer starts of 3D NAND shipped capacity will be installed by the end of calendar 2014.

In addition, in recent weeks, 2014 planar NAND investment plans to transition the 16-nanometer devices have solidified for more than one customer. Overall, we still expect supply bit growth to be in the low 40% range.

On a combined basis, we forecast memory spending will increase by 10% to 20% year-over-year, with wafer fab spends between $12 billion and $13 billion, representing an increasing proportion of WFE year-over-year at approximately 40% of the total.

Adding this all together, our outlook for 2014 wafer fabrication equipment spending, with a midpoint of $32 billion, would represent the fifth consecutive year with relatively healthy and disciplined equipment spending.

It's always important to note that visibility beyond this quarter and especially into the second half is clearly more limited than the near term. Where we ultimately end up in our WFE range will largely depend on production readiness and market acceptance of the technology inflections just highlighted.

In this positive industry environment, which for Lam, is supplemented by inflection-led addressable market-size expansion and target market share growth, I'm very encouraged by our industry outperform opportunity.

With the transition to 3D NAND, we've gained strong production tool decisions, maintaining our lead in etch while driving significant gains in deposition.

Our pipeline of new products were key to our success, including our next-generation dielectric etch module, our new highly productive dielectric deposition platform and our differentiated tungsten CVD system.

We are well-positioned with each of the 3D NAND pilot lines, we believe, and are focused on achieving, at a minimum, the same degree of success as production tool decisions are finalized.

We believe that we have additional opportunities to gain applications through the transition to second and third-generation 3D NAND devices, where the increased number of alternating films also proliferates the complexity of the etch and deposition processes. We're actively engaged with the customers to address those challenges.

In the area of multi-patterning, our conductor etch business is benefiting from the increased number of multi-packing steps required with the transition to smaller device geometries.

Although device dependent, we see emerging evidence of slightly more than our early estimates of 8 to 10 new multi-packing steps in a 20-nanometer logic device for foundries, compared to a 28-nanometer baseline and the 12 to 13 steps for 16- to 40-nanometer devices.

In DRAM, the number of multi-patterning steps more than doubles with the transition to 20-nanometer going from 3 or 4 in a mid-2x device to between 8 and 10 at 20-nanometer, with the same evidence of upsize on number of passes. You should expect more specificity from Lam on this in the coming quarters.

This transition also presents growth opportunities for our deposition business. Many of the spacer-based, multi-patterning deposition steps can be done with batch variances [ph] today.

However, customers are evaluating or starting to transition these steps to single wafer atomic layer deposition, or ALD tools, as the film conformality and uniformity requirements increased.

We're engaged with multiple memory manufacturers with their offside ALD tool and, based on the feedback received so far, believe with continued hard work we are well-positioned for production tool decisions expected this year. In logic, we often talk about the transition to FinFET structures and the complexity around the transistor.

However, the complexity in the back-end is growing at a rapidly accelerating pace also. As transistor densities in these devices increase, the wiring schemes required to connect these transistors become more and more complicated. Starting around the 32-nanometer node, customers introduced a metal hard mask x scheme for a couple of wiring layers.

The number of layers has grown with each successive node and Lam stands to benefit as the clear market leader for this application. To maintain device reliability and performance, customers began adopting film treatments and other processes that play into a few of Lam's strengths.

Our solar, ultraviolet thermal processing tool is the market leader used to improve the integrity of ultra low k films, predominately for leading edge logic devices. The number of layers required in UV cure of low k dielectric films is also increasing with each successive node; again, a positive opportunity for Lam.

With thinner and more closely packed films, reliability of top lines is becoming more of a challenge. Lam has developed a unique film pretreatment module which enhances reliability and reduces resistance, a factor in device speed.

Our solution was recently selected for next-generation logic devices and we expect to ship production tools through this year. In single-wafer clean, we will have shipped our third next-generation spin clean system as planned in the next couple of weeks.

These tools are being installed at leading memory and logic device manufacturers and are being evaluated for a broad range of applications, including front-end-of-line.

It's still early, but the initial progress and process data we have received is in line with expectations and the intensity of managing yields to a higher definition access for our customers, clearly very relevant for evaluating that opportunity.

We would expect to have broader reliability and process data towards the middle of the June quarter to begin making assessments on how the tools are performing relative to our customers' requirements and our competition in the second half. As we embark on 2014 and beyond, we believe the opportunities available to Lam Research are significant.

We're focused on exploiting those opportunities to their fullest by continuing to strengthen our competitiveness. We're increasing the magnitude of new product releases and customer engagements, particularly in the areas of dielectric etch, atomic layer of deposition and single-wafer clean.

We're starting to execute newly developed operational plans to drive efficiencies across many aspects of the business, targeted at achieving our 2015, '16 performance ambition.

We're reducing our emphasis -- sorry, we're reinforcing our emphasis on customer trust, broader collaboration and strategic relevance to our customer in light of semi equipment consolidation trends. Today, we are very focused on achieving our long-term growth objectives, competing as one integrated company.

We have tremendous strength in the capability and commitments of the whole Lam Research team and I would like to take this opportunity to thank each and every employee for their contributions last year, and wish them success in pursuit of our 2014 vision, a year where, at the $32 billion WFE level, we anticipate increasing our operating income over 2013 at twice the rates of our revenue growth; further, growing cash from operations year-over-year at twice the rates of operating income.

With that, I will turn the call over to Doug to discuss December quarter financial results in more detail and provide our guidance for the March 2014 quarter..

Okay. Thank you, Martin. Good afternoon, everyone, and thank you for joining our call. We finished calendar year 2013 on what I believe is a very strong note. Shipments for the December quarter reached an all time high. We achieved record revenues for a third consecutive quarter.

We grew operating profit more than 2x as fast as revenue, and we delivered earnings per share above our expectations. This financial performance comes partly as a result of us delivering on the promise of bringing Lam and Novellus together. Let me now provide a little more detail of our December quarter.

Shipments increased by 15% sequentially to $1,139,000,000 which was slightly above the midpoint of our guidance range. Consistent with our expectations, we saw strong growth in memory shipments, as well as a sustained level of foundry spending. The combined memory segment represented 64% of total system shipments and this was up from 48% in September.

NAND system shipments contributed 36% versus 28% in the prior quarter, and includes shipments to the first 3D NAND production facility. We saw a sizable increase in DRAM shipments, which represented 28% of system shipments, which was up from 19% in the September quarter.

Foundry shipments were 28% of total system shipments, and this was down from 36% last quarter. On an absolute dollar basis however, foundry shipment system -- or foundry system shipments were relatively flat, supported by ongoing investments for the 20-nanometer node. The remaining 8% was made up of logic and other shipments.

Revenue for the December quarter was $1,116,000,000. This also was slightly above the midpoint of our guided range and was 10% higher than in the September quarter. December gross margin percentage came in pretty much as we expected at 48.5%, which was stronger than our 2013, '14 financial models.

This was an 80 basis point increase from the September quarter. We benefited from a favorable product mix during the quarter. And as I've shared with you before, our gross margin performance is impacted by many factors, including product mix, customer mix and overall business volumes.

Increasingly, as we're running at close to full utilization, the impact of volume is less important than the product and customer mix changes. Nonetheless, we will see quarterly fluctuations in our gross margin performance depending on all of those variables.

For the calendar year, our gross margin performance of approximately 45% was fairly consistent with our financial model, and we continue to point to our financial model as the best proxy for our financial performance, including the timing and WFE reference points.

Operating expenses for the December quarter increased to $302 million, consistent with our expectations. On a percentage basis, our December quarter expenses were 27% of revenue, and this compares with 29% in the previous quarter. R&D as a percentage of total operating expenses was 58%.

We continue to invest in next-generation products and technologies to strengthen our competitive position for the long-term success of the company. Operating income increased by 27% to $209 million in the December quarter and this compares with $165 million in the September quarter.

Our resulting operating margin was 18.7%, pretty much as we expected, and I think shows the operating leverage in our financial model. Other income and expense came in with a positive impact of several million dollars relative to our original expectations.

This was primarily due to a strong stock market in the quarter and its resulting impact on our deferred compensation investment portfolio. Our tax rate for the December quarter was approximately 9.3%, which was consistent with our planning assumptions.

And I continue to expect the tax rate in the low to mid-teens will carry through the remainder of the 2014 fiscal year. Based on the share count of approximately 172 million shares, earnings per share for the December quarter totaled $1.10. This result was better than forecast coming into the quarter.

And I should point out the share count includes the dilutive impact from our 2041 convertible note of approximately 6.6 million shares, and that was based on an average quarterly share price of $52.52. And I'll just remind you that we include a schedule on our IR website that shows the impact of this note to help you in your planning.

During the December quarter, we spent $40 million on the repurchase of approximately 760,000 shares of common stock with an average price of $52.20. At this point, we have completed more than half of our current $250 million authorization.

This level of buyback will help us accomplish our objective of managing the dilution from our employee equity plans. I'd also just point out, we're well on track to complete this authorization in calendar 2014. Let me now take you through the balance sheet.

We ended the quarter with gross cash and short-term investments, including our restricted cash of $2.7 billion and this compares with $2.6 billion in the September quarter. Our cash balances remain roughly 25% onshore and 75% offshore.

We had deferred revenue of $405 million, which does not include the $54 million in shipments to Japanese customers, which will convert the revenue in future quarters. DSO for December was 74 days and this compares to 64 days in the September quarter.

And as I mentioned on last quarter's earnings call, we expected shipments to be back-end loaded in the December quarter. Due to the timing of customer projects, this profile was somewhat more pronounced than we originally anticipated. Inventory turns came in at 3.8, and that's flat with the prior quarter.

Cash from operations was $129 million or 12% of revenue. This was up from $52 million in the September quarter. Our operational cash generation was impacted by growth in accounts receivable. Over half of our quarterly shipments occurred in the month of December itself.

This translated into less of our receivable balance being due before the end of the quarter. When business volumes are ramping as we are today, it's typical to see growth in working capital, and we did see that.

Our current quarter outlook for the March quarter reflects a much more linear shipment profile and I expect operational cash flow to more closely approximate operating income next quarter. And I thought I'd just mention, I expect 2014 will be a very strong year for Lam Research's cash generation.

Company noncash expenses include, among other items, $23 million for equity comp, $41 million for amortization and $33 million for depreciation. In the quarter, we incurred $38 million for capital expenditures and we exited the quarter with approximately 6,550 regular full-time employees. Let me now turn to our guidance for the March 2014 quarter.

This is our non-GAAP guidance, I should point out. We expect shipments of $1,250,000,000, plus or minus $30 million, reflecting continued strength in the memory segment and ongoing investments for 20-nanometer foundry capacity. We expect revenue of $1,215,000,000, plus or minus $30 million.

We currently expect higher customer concentration in the March quarter, with nearly 80% of our system-related sales derived from our top 3 customers, versus approximately 60% in the December quarter. We expect gross margin of 45%, plus or minus 1 percentage point.

In the March quarter, we have a higher proportion of newly introduced etch and deposition products, which has a slightly negative impact on gross margin, while those products are in the early phase of their ramp. We forecast operating margins of 19.5%, plus or minus 1 percentage point.

And finally, earnings per share of $1.15, plus or minus $0.05, based on a share count of approximately 173 million shares. Operator, that concludes my prepared remarks. Martin and I would now be pleased to take your questions..

[Operator Instructions] And our first question comes from the line of Harlan Sur with JP Morgan..

Great job on the quarterly execution. On the 3D NAND side, I think the team has mentioned previously, your views that it's predominantly one guy in the market this year. I know that at least 2 of your memory customers that have recently talked about some 3D NAND activity later this year or early next year.

Just wondering if you're seeing this now in the product pipeline for the second half?.

Thanks for your comment at the introduction there, Harlan. The answer to your question is yes, we are. I expect, still, one customer to be the dominant kind of emerging out of pilots to production. And to the extent that other customers are investing in 3D NAND, which we do expect, there are pilots-oriented investments.

But it is more than a one-customer assumption set that's embedded in our $32 billion, correct..

Great.

And then on your significant installed base, your services business, how do you expect the growth here relative to your overall businesses this year? Industry utilizations, I would think, are trending higher, and so what are -- and then on top of that, what are some of the specific initiatives both sort of top line and cost and expense front that the team is going to be focused on this year with respect to services?.

I think on the utilization front, kind of, time will tell. I mean, instinctively, I agree with the hypothesis of your question but it's not as if, with some rare exceptions, utilization levels are -- they're kind of not -- are kind of low there. They're pretty active.

I mean, certainly in the memory space, that's a true statement and I think the technology nodes, given the flexibility the foundry community have, utilization pretty high there as well. But indeed, to the extent utilization goes up, that's one source of growth. Another source of growth is the installed base of the company.

So there's a natural expansion of the growth consistent with the output of the company. And you can see evidenced by our actual performance and forecast, we've got some nice momentum on outputs of systems into the installed base and that bodes well for sustainable growth this year into next year.

And as we talked about in our Analyst Meeting and a little bit in the last 2 earnings calls, the installed base business of the company, the spares, the service, the upgrade, the training, the refurbishments, are tremendous opportunities to contribute value to the customer and that being a core strength of the history of both companies.

But I would say it is fair to characterize that we're reenergized around that today. And in the context of responding to complex challenges from our customers, to not just deliver technology but to deliver cost. That's an opportunity for us to strengthen partnerships with our customers..

Our next question comes from the line of Timothy Arcuri with Cowen and Company..

A couple of things. Relative to WFE for 2014, we're sort of exiting December at this sort of $33 billion run rate as an industry. I'm not sure if you think that, that's the right number but that's what I calculate.

So if the year is going to be sort of $32 billion, I think you're saying, and if the first half is going to be better, does that sort of imply that the year is going to be front-half loaded or you just don't have visibility into the back half? And if it's better, then the year would be higher than your $32 billion number..

Well, I think as I said in my prepared comments, we obviously have less visibility in the second half than first, but we do have some assumptions, which are based in that $32 billion. And I think reasonable balance between first half and second half is kind of an overall commentary I would offer for WFE in total.

But I would say one segment that stands out in that kind of picture is DRAM, where I think there is a higher profile of first-half investment compared to the second. And I don't know if that's a 60-40 or a 55-45 or a 65-35, time will tell.

But that is the segment which stands out, at least at this point, as being slightly more biased to the first half.

Now, a lot of things could change in either direction and, clearly, to the extent that prevails, that's an opportunity for Lam to outperform, given kind of memory concentration in the first half compared to the second half as far as peer comparisons are concerned. Although as I said, I do expect outperformance in the calendar year period.

So that's the best I can offer you at this point, Tim..

Okay. And just as a second question, you had a pretty big quarter for NAND obviously, in December.

Do you have a sense of what the shipment mix is going to look like in March? I would assume memory is going to be maybe down a smidge and foundries up, but can you give us a sense?.

No, I think actually that we've got memory expansion in shipments December to March and foundry, fairly stable..

Yes, that's exactly what we're expecting..

Our next question comes from line of Patrick Ho with Stifel, Nicolaus..

And likewise, congratulations on a great 2013.

Martin, first, in terms of kind of big picture looking out over the next couple of years in terms of your market opportunity, with the continued delays in EUV, have you made any revisions to your, I guess, target models in terms of both etch and deposition over the next few years, particularly as you look at 2015 and 2016, given the pushouts that have occurred?.

That's a good question. Thank you for your comments at the beginning as well. We have not chosen to revise the models for '15 and '16 yet. I think, clearly, we would be looking for incremental opportunities to the baseline that we established if indeed the EUV picture, as recently characterized, plays out that way.

And we've got a lot of time between now and then in terms of positioning for 7-nanometer logic, particularly into the extent there is any interception at 10. Frankly, 10-nanometer positions are still out there in many respects, as well.

So we haven't changed the model per se, but I would expect us to be chasing a broader set of opportunities as a result of this..

Great. And maybe as a follow-up question to some of your prepared remarks about the DRAM opportunity, particularly for double patterning at 20-nanometers, you talked about the different layer opportunities that increased.

Can you maybe go a little more specific in terms of where you see the greatest opportunities within etch, kind of on a more granular detail, as well as the opportunities in deposition? Where specifically do you see the greatest incremental opportunities as you move to 20-nanometers from DRAM?.

Wow, that's really specific.

One of the things I don't want to do, frankly, is get a little bit ahead of ourselves on the number of extra passes, which is of the most tangible area of growth for us in the DRAM conversion and -- because I want to see more evidence that, actually, the emerging messages that I communicated to you today actually show up on a continuing basis.

But we're really focused on high aspect ratio opportunities. We're really focused on -- in the x space, we're really focused on packaging and ALD with conformality and uniformity challenges being more significant in next-generations. That's the area for us.

I mean, it's all about inflections and it's all about emerging technologies to support narrowing kind of requirements on process windows that are tough to deal with..

Our next question comes from line of Jim Covello with Goldman Sachs..

Martin, just a clarification first.

You said memory up 10% to 20% this year, that was including both DRAM and NAND?.

Yes..

Any chance of giving us a breakdown in terms of how you think each of those markets grow this year?.

Indeed, I could probably give you some reference on that. If you have a follow-up question, why don't you ask that first and I'll do a little bit of research while you're....

Sure. The follow-up would be understating your comment about 60% of the business coming from the top 3 in December and 80% from the top 3 in March.

Within NAND, specifically, are the -- is the remainder of the 40% and 20%, respectively, are there other NAND players in there as well or is NAND very top-heavy loaded?.

Well, I mean, there are only kind of so many players, obviously, in the NAND space. And the mixture of spending has kind of 3 components to it. It has a 3D investment, which in '14 is different than '13 by virtue of more people engaged in a pilot line space. So that's one investment type.

Another investment type is whatever additions are going to be made in the context of remaining planar investments. And then a significant investment in NAND flash comes from conversions. And that's obviously a play in a dominant conversation for the customers.

So if I looked at additions, I would say the additions via 3D NAND, and if I look to upgrades, it's all about kind of planar investments. And I would not expect this year to be the year where, all in, 3D is the majority of NAND investments.

So if I look at the sum of additions and upgrades and conversions, I would say calendar '14 is still likely to be -- it's getting closer, but it's still likely to be a planar majority year. So the answer to your first question is, obviously, the baseline for NANDs WFE in '13 is a little higher than DRAM.

We assume about $6 billion for NAND last year and $5 billion or so for DRAM. I believe there's about $1 billion or so of growth in NAND year-over-year. And frankly, something similar to that level in DRAM as well. So reasonably equal growth increments, slightly different baseline..

Our next question comes from the line of John Pitzer with Credit Suisse..

new product ramps and customer concentration.

I'm kind of curious if you could help me quantify what kind of hit those 2 dynamics are having in the March quarter and how we should think about those dynamics throughout the year as we think about gross margins?.

I mean, I'm guiding you down -- John, this is Doug -- 80 basis points from what we just delivered. I'm not going to quantify the specific impact of each of those, but they both contribute, obviously offset a little bit by slightly higher volumes.

But as I tried to indicate, the volume bit is getting to be less and less important because we're running the factories pretty full right now. So the upside from that is less today than it has been in the past..

And I would add, I think an important point relative to the interpretation of the financial models. So if you kind of go back to what we presented at SEMICON West last calendar year, you get a '13, '14 model and a '15, '16 model.

And the fact that we had 2 models was intended to be important because it does take time as well as volume to execute cost reduction plans in terms of developing new products for lower cost profiles, et cetera, et cetera.

And it does take time to execute and implement strategic plans to improve the performance of the company, however good we are in terms of competency and capability and execution. So the '13 and '14 model had a 45% placeholder and, within reason, that's a great place to be in terms of kind of modeling.

And just occasionally, we're going to pop up above it as we did in December. And maybe just occasionally, we popped below it. It's much less about volume at this point. We need time to kind of get us through this period of the penetrations on the inflections.

So we come out of the gates and you launch a new product, it's usually at its lowest profitability point in that first 6 months to 1-year time horizon. And the inflections are becoming a greater proportion of the output of the company.

And '15 to '16 is a great placeholder for when the majority of that inflection and the majority of the new products associated with it, which should be firing on all cylinders from a cost point of view at that point, have their impact on the company.

So I'd ask that you all think through not just the volume, but the timelines that were defined in the models that we communicated last year..

That's helpful. And then, Martin, as my follow-up -- I appreciate the detail, as always. As we think about EUV getting pushed out, I think one of the things we're seeing is the chip companies are getting more efficient on multi-patterning. The largest foundry guy was not expecting a density improvement at 16; now he's talking about it.

The largest logic guy is talking about being able to stay on Moore's Law, even without EUV for a lot longer than we thought.

And I guess my question to you is, I'm trying to understand if they learn to be more efficient with multi-patterning, does that actually take market opportunity away from you? Or are they becoming more efficient because of what you're providing?.

I mean, I'm sure all of you have obviously asked that question. I mean, the perpetual challenge in this industry is bringing technology to the customer at lower cost, bringing capacity and outlook to the customer at a low cost.

And so I am sure and hope, quite frankly, that we're enabling not just technology roadmaps to customers, but cost reduction roadmaps to customers because I think we all recognize the complexity of our customers' industry and our customers' customer industry for that matter. So we have to run Lam Research with a long-term perspective in mind.

And so I always think it is very artificial to try and bias performance in the short-term by not delivering solutions to the customers that in the long term will allow them to be most successful.

So I'm sure we're part of enabling and, indeed, the customer by virtue of consolidation and influence over the equipment industry, brings a pretty big back to the table as well..

Our next question comes from the line of Stephen Chin with UBS..

Just one follow-up question on WFE.

If the industry spends more than your initial view of $32 billion, where do you think the upside would come from? Do you think it would be higher foundry or would it be on memory side?.

I think it's kind of a couple of things. There's a demand story, so I don't think $32 billion is the most aggressive view of kind of GDP in consumer confidence. And if that kind of trended up, there's -- I think, there's a little bit of upside there.

The other part of it, to your point, frankly, is emerging evidence of cost and performance benefits of inflection-led device transition.

So if the industry sees cost and/or performance benefits, I guess, the industry of our customers' customer sees the benefits, then there's likely to be an acceleration, if history is a relevant indicator of our future. What the probability of that is at this point? I have no idea, which is why I gave you $32 billion, plus or minus $2 billion..

Yes.

Okay, and there wouldn't be any -- it wouldn't be like memory over foundry if there was some upside?.

I think I wouldn't characterize, one way or the other at this point, which one I thought was more likely to happen. There are clearly independent variables on the supply side. They're very dependent on the demand side, so I don't know. It could go either way..

Our next question comes from the line of Krish Sankar with Bank of America Merrill Lynch..

Martin, I had 2 questions.

Number one, in terms of the 3D NAND on the etch side, is your market share similar or better or lower compared to planar NAND?.

It's at least as good and I would expect in some of the selection spaces, slightly better..

Got it. That's very helpful. And then one other question. In terms of your industry outlook, you said that you're seeing a lot of reuse of equipment on the logic side, which is kind of not a big surprise.

The question I was trying to find out is are you seeing with capital, in terms of in the foundry, is still very high? Are you seeing more reused inventory from the foundry customers or do you think that's going to happen going forward?.

I think it will be an emerging trend. I think it's a very hard thing to execute and, at some level, the need and the expectations for it are obviously embedded in the numbers we've given you on WFE. But I think the economic realities of scaling for the foundries make it much more important than ever.

And the challenge obviously, is if they have sustaining commitments from their customers, so the legacy geometries how do they ever free up the capacity to make it kind of happen on scale. So I think it shows a -- more how big it ultimately is. I think time will tell..

Our next question comes from the line of Mehdi Hosseini with SIG..

My question is for Doug.

Do you have any plans to help increase the cash onshore as a means to increase shareholder return?.

Mehdi, I kind of described our approach to cash is we've got a plan in place at least through 2014, which is the $250 million buyback authorization. Yes, we're always looking at opportunities and whether they're -- crude guidance I've provided is roughly 20% of the prospective cash we generate is onshore. We may be able to tick that up a little bit.

In fact, I think we will. We're always looking at a couple of different things and we'll communicate with you kind of year-by-year or quarter-by-quarter as we work our way through this authorization, what the concrete plans of the company are as we go forward..

And my brief follow on is for Martin.

Do you have any market intelligence, especially from downstream players to help us understand the application for 3D NAND use, especially with the 80,000 to 100,000 wafer per month capacity that you were referring to?.

I think we do, but I'm going to reserve the right to keep that to our ourselves and respect the interest of our customer..

Can you talk around it or qualitatively talk about some of the general use of the 3D NAND?.

I know you don't like me doing this, but I am going to resist it because I feel like we put a lot of information out and, just occasionally, I got to stay honest and protect some of what we spend lots of time building, which is relationships with customers and customers' customers, so that we have a good a sense of where the industry is headed..

And you're saying that this 80,000 to 100,000 would be installed by September so that it would -- the shipment would start by December? Is that right?.

No, it's a statement of physical shipments to customers. So by the end of the calendar year, that is the number I gave you..

I show that because the Korean customers have both told us....

Mehdi, we're going to move on here now.

Could we get the next question, please?.

Our next question comes from the line of Mahesh Sanganeria with RBC..

Martin, a question on the foundries, the linearity of 20-nanometer ramp up. You talked about the ramp base dependent on the availability of the technology.

Where do you think the 20- and 14-, 16-nanometer are in terms of readiness? And from that, what can you tell us about the ramp profile of these technologies?.

Well, I think, kind of back to my earlier statements, the assumption that we're making today based on our conversations with customers and our own modeling is that foundry is a reasonably stable year. It's going to have, obviously, a majority forum 20-nanometer for first half and 14, 16 emerges in the second half as kind of pilot lines.

So you're going to see a different node of spending in the calendar year. And if nothing changes in terms of commitments of the customers' customer to FinFET devices, then the rates by the foundry to kind of get whatever early share momentum is available tends to suggest a pretty kind of convicted spending to that plan.

And I don't think this is the year where a 14 to 16 investment is particularly subject to risk on yield because it will be too early, it's not enough. I mean, it will be a much more relevant conversation in calendar '15.

If 14, 16 yields aren't where the customers want it to be, then I'm sure that will be relevant to the pace of the add capacity, but I don't see that as being a particularly big factor in calendar '14..

Okay. That's very helpful. And then you made comments regarding space or double patterning driving ALD.

My question is, is there a significant adoption of spacer-based double patterning in the DRAM and the logic devices? I know NAND is 100% space to double pattern, but are you seeing a lot of interest from DRAM, as well as logic devices?.

DRAM, yes..

Our next question comes from the line of Ben Pang with Northland Capital Markets..

In terms of the reuse, can you characterize the amount of reuse for your equipment, 28- to 20-nanometer and 20 to FinFET, and kind of split that between etch and CVD?.

You need to ask that question again because you're breaking out. Sorry..

If you look at the equipment reuse between 28-nanometer foundry logic and 20-nanometer, and then similarly 20 to 16 or 14 FinFETs, what's the difference in the amount of your equipment that can be reused? And is there a difference between etch and CVD?.

Okay. The etch and CVD conversation's a little bit premature for me to have. And the first one -- the first piece, it's a little difficult, but the best I could give you probably is that I think in general, the equipment set for 20-nanometer generally is much more overlapping with a 14 and 16 equipment set than was true for 28 to 20.

So I would say, intuitively, it would seem there are more opportunities for reuse 20 to 14 to 16 than existed 28 to 20. Now, that's a line availability statement as an -- or ease of transition.

That doesn't take off the table, the challenge I described a little earlier, which is if you got demand from a customer and you have legacy demand for some years, how do you free enough capacity to go do it? But intuitively, I think that the reuse opportunity for the foundry is greater 20 to 14, 16, presuming you have 20 investments of a sufficient amount than was true at 28 to 20..

Okay. And my follow-up is that you talked a little bit about the customer concentration.

For 2014 calendar year, do you expect the same customer concentration as 2013?.

No. Actually, I think it will be a little bit less. When we look at it, I mean, the March quarter is pretty concentrated. I think the whole year is actually going to be the same or maybe even a little bit less than '14 relative to '13..

Our next question comes from the line of Edwin Mok with Needham & Company..

First question regarding the industry. Just on your foundry, WFE a little [ph] up 10% to 20%. I was wondering how much of that comes from kind of increased capital intensity in your foundry versus broadening of customer base? We heard from one of your peers talk about they saw some trailing etch to the order pushed out at the foundry side.

I was wondering if that had an effect on how you think about the foundry position. [ph].

I don't think that dollars invested in '14 and '16 will be as high as 20% in the calendar year.

That's the assumption that we have at this point and we have said -- and we're much more able to speak to this for deposition etch and cleans than we are wafer fab as a whole, but we've kind of sized the increment in SAM to the 5% to 10% level, I think, for the comparison of final generation planar, first generation FinFET for foundry.

So that's kind of the best I can give you on capital intensity..

All right. I see. Okay. That's fair. And then I think you mentioned about one of the largest service contract you signed on the quarter and try to focus on the service area.

Any way you can kind of quantify how much of your business is service right now, how do you think that will transpire as we go, look beyond this year, let's say '15, '16? Do you expect a greater growth in that area? And any kind of metric you can add that does kind of measure that?.

Yes, I think actually, we gave a pretty good shot at answering that question in the Analyst Meeting at SEMICON West last year, so I'd kind of refer you back to the July 9 presentation. There's kind of more substance there than we have time for today. But just so we're not confused, it's not just kind of a service play. It's an upgrade play.

It's an installed base utilization play. It's a reliability play. It's training. It's everything that's available to us as an equipment company, supporting our customers' installed base improvement expectations. Service is one part of that, but it's not a growth plan limited to service..

Operator, I think we have time for 2 more questions..

Okay. Our next question comes from the line of Terence Whalen with Citi..

Actually, 2 quick ones. First, you gave the 80,000 to 100,000 3D NAND installed capacity by the end of '14.

Can you just help us understand what that number was end of '13?.

I think we had like 20,000 to 25,000 as the communication at the end of last year..

Yes, I think we said 20,000, Terence..

Okay, terrific. The second question is on customer concentration. Starting at 80% in that first quarter, it implies a pretty sharp broadening in the second half of customer shipments.

Can you just explain to me how you expect that to develop sequentially and, again, remind us what '13 was? And I ask that because with the context of understanding whether conviction in those shipments and the timing and assurance of those shipments is higher or lower than with the larger customers?.

Terence, I think the most concentrated quarter is going to be the March quarter. I'm not going to get into the specifics of each quarter after that because things move around, but it will broaden out our view as we get through the remaining quarters..

I don't know, to the kind of soft part of your question, is it a higher risk or a lower risk to have more people participating? Who the hell knows.

I tend to feel that the reasons for more people investing and there are more reasons around -- technology inflections inherently have more conviction than kind of genetic capacity additions, so I actually feel pretty good about that.

And I also feel like the environment, the supply and demand balance and the fact that we come into the year pretty tight, the fact that pricing levels for memory, the fact that the profitability levels for semiconductor companies generally is -- maybe they would argue not as good as they'd like it to be, but it's far better than it has been.

And so I tend to feel better about it. I do think that you should, we should continue to expect variability quarter-to-quarter. I mean, it is really hard to predict the output of these companies when 2 to 3 to 4 guys can represent everything about the performance of your company. One guy can move left or right and you've got a different picture.

And we've kept our ranges pretty narrow on our guidance and we'll keep them that way as long as we feel like we can manage it. But I would say it's getting much more difficult to manage variability of kind of individual customer movements than ever before..

And our next question comes from the line of Vishal Shah with Deutsche Bank..

This is Chad Dillard on for the line of Vishal.

From the industry's perspective, can you talk about how you see the amount of 20-nanometer being installed for 2014 from a wafer start perspective?.

Yes, given the concentration of a couple of customers, I'm going to kind of resist that level of specificity. It's, as I said, I do expect the -- maybe you got to triangulate a little here. We are forecasting in the range of $13 billion, $14 billion of WFE.

I think kind of the public commentary and analyst commentary on 20-nanometer cost is approximately $1.25 billion, $1.3 billion per 10,000 wafer starts addition. And I kind of said I expect that the 20-nanometer addition is greater than the 14 and 16 addition.

I think if you kind of work with those data points, you're going to find out a pretty reliable answer to your question..

Great. And maybe you could just unpack the foundry shipment, the number in December.

What was the mix of 20-nanometer versus the rest?.

We don't -- that's disclosure above and beyond what we have customarily done, I'm sorry..

Thank you, and I would like to turn it back over to management for closing remarks. Please go ahead..

Wonderful. We truly wish to thank you all for spending the last hour or so here with us today. As a reminder, a webcast replay of this call will be available later this afternoon on our website. So on behalf of the entire management team here, we would like to -- we appreciate your interest in Lam Research..

Ladies and gentlemen, this does conclude our conference for today. Thank you for your participation. You may now disconnect..
