Good day and welcome to Lam Research September Quarter Earnings Conference Call. At this time, I would like to turn the conference over to Ms. Tina Correia, Corporate Vice President of Finance and Investor Relations. Please go ahead, ma'am.

Thank you, and good afternoon, everyone. Welcome to the Lam Research quarterly earnings conference call. With me today are Tim Archer, President and Chief Executive Officer; and Doug Bettinger, Executive Vice President and Chief Financial Officer. During today's call, we will share our overview on the business environment and will review our financial results for the September 2020 quarter and our outlook for the December 2020 quarter. The press release detailing our financial results was distributed a little after 1 o'clock PM, Pacific Time, this afternoon. The release can also be found on the Investor Relations section of the company's website along with the presentation slides that accompany today's call. Today's presentation and Q&A includes forward-looking statements that are subject to risks and uncertainties, reflected in the risk factors disclosed in our SEC public filings. Please see accompanying slides in the presentation for additional information. 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 o'clock PM, Pacific Time. A replay of this call will be made available later this afternoon on our website. With that, I will hand the call over to Tim.

Thank you, Tina. And welcome, everyone. Lam delivered very strong September quarter results. Revenues and gross margin came in above the midpoint of the guided range. Operating margin and diluted earnings per share exceeded the high end of the range. Our performance reflects solid execution across the company. The operating environment remains challenging due to the COVID-19 pandemic, but the tremendous dedication of Lam's employees and our partners worldwide is enabling us to perform at a high level. Notably, the September quarter marked record revenue and diluted earnings per share for the company and was also the first quarter in which we have exceeded $1 billion in revenue from our customer support business group. At the midpoint of our December quarter guidance, we will be growing EPS more than 35% year-over-year in 2020. Investments we are making in manufacturing and supply chain resilience are enabling us to meet customers’ critical needs in a period of strong demand and are preparing us for the continued growth we see ahead. Before I talk about market and product trends, I want to touch upon China-related trade regulations. As has been widely reported, U.S. regulations have impacted our ability to ship wafer fab equipment and parts to a large foundry customer in China. We're working with regulators on this issue and have applied for licenses to ship equipment and parts that are subject to restrictions. As a result of the current situation, our December quarter guidance reflects an impact to sales to this customer. From a market perspective, we see positive momentum in the underlying drivers of semiconductor growth and believe this translates into a healthy outlook for Lam's business. Work and learn from home trends continue to drive demand in key electronics categories, including PCs, storage, and networking. Third-party data suggests that growth…

Thanks, Tim. Good afternoon, everyone, and thank you for joining us today. I hope everyone has continued to remain safe and healthy. We're extremely pleased with our operational and financial execution in the September quarter. We delivered record performance in multiple areas, including total revenue, which came in at $3.18 billion. And as Tim mentioned, as part of that revenue, we achieved over a $1 billion of revenue in our customer support business group. These results are clear evidence of our ability to grow the company and meet the needs of our customers while further improving our business resiliency. Our September revenues increased 14% from the June quarter driven by customers’ technology investments to meet long-term growth opportunities. These opportunities range across multiple vectors such as data centers, 5G networks, smartphones, gaming consoles, and personal computers. In the September quarter, we also had a record level of earnings per share coming in at $5.67, the results of our solid revenue and gross margin performance. Let me now move on to provide some color on our systems revenue. There were continued strong investments in the Foundry segment, and we had the highest system revenue dollars per foundry in our company's history. Our customers invested broadly with spending targeted at 14, 7 and 5 nanometers. Foundry represented 36% of our systems revenue for the September quarter. The Memory segment was also strong in the September quarter coming in at 58% of systems revenue. NAND represented 39% of our system quarter revenue with investments spanning 64, 96 and 128 layer devices. We saw increases in DRAM spending, which contributed 19% of our systems revenue, which was up for 16% in the June quarter. Customer investments focused primarily on node transitions to 1y and 1z. We continue to see memory bit supply growth in…

Thank you very much. [Operator Instructions] We'll go ahead and take our first question from C.J. Muse with Evercore. Please go ahead.

I guess first question on the NAND side. I think there's a notion that perhaps we might be nearing the peak on spending. So, we'd love to hear your thoughts on: A, how do you think about your revenue opportunity on just node migration versus new wafer starts? And then B, can you kind of walk through the revenue opportunities, which sounds like it’s increasing as we migrate from the 9x layer node to 128 layers and above?

Sure. Let me start C.J. Yes, I think that, you probably called out the most important point right there at the end. What we have continuously said is that, because of the role that etch and deposition play in building devices, our opportunity is growing quite significantly at two of those node migrations. And so, from our revenue perspective, we clearly see that, that revenue continues to grow in 3D NAND into the future. From a spending perspective, obviously, anytime you continue to see higher and higher numbers, you can start to think about a peak. But again, if you looked at and thought about what I said about supply growth, we still see ourselves exiting this year with supply growth remaining below the long-term trend line. And also if you go back and reference the data point we've given a couple of times at the NAND Flash at the Flash Memory Summit, about five year spending requirements to meet what we see as long-term demand growth in the high 30% range. That is -- we're kind of nearing those spend levels right now after a couple of years previously of underspending that. And so, I think that we're still quite confident about how we enter 2021 from a NAND spending perspective.

And as my follow-up, on the CSBG side, you saw great acceleration on a year-over-year basis I think, up 29%. So I was just curious, is that a function of higher utilization rates of customers? Is there kind of one-time upgrades in there or is that tools coming off warranty? And as part of that, how should we kind of think about the growth trajectory of that business for all of fiscal ‘21?

Sure. Well it’s -- maybe the last part first, which is, as Doug pointed out, probably the best way to think about its future growth is still the same as what we said in March, which is a 40% growth between out to 2023, but we did see an acceleration. And I think what you're seeing is in some ways the power of that business, which is made up of several different components, you pointed out some of them, a sensitivity utilization which is primarily in the spares business. And then also as customers look to get more out of their existing installed base, I mean, a lot of my script talking about how customers are looking for ways to enable these transitions and enable high volume manufacturing ramps, but we are sensitive to how much it costs to do that. And so, customers continue to look for technology and productivity upgrades to make those installed bases as valuable to them as possible. So we have seen upgrades increase in terms of that. And then I also mentioned, spending on refurbishment and other systems as well. And so, it's a multifaceted business and I think that right now we're hitting all of the angles that are very important to our customers.

And we’ll go ahead and take our next question from Harlan Sur with JPMorgan. Please go ahead.

Great job on the quarterly execution and strong results. Yes, it's been two years of sort of weak flattish DRAM spending. But as the demand profile looks strong next year, and you have the early move to run alpha node, 2021 is looking like a growth year for DRAM spending. And on top of that, memory architecture has always been very 3D-like, and similar to NAND-like. Aspect ratios are increasing, tighter tolerances on material thicknesses and so on. So ahead of this strong DRAM year, how do you view your SAM and share expansion potential on some of these next generation 1-alpha DRAM architectures?

Yes, just to kind of reiterate comments we've made in the past. I mean, we -- as you pointed out, every time you move forward in technology, whether it's 3D NAND, we just spent time talking about or hearing DRAM. The features are getting taller. The aspect ratios are getting more difficult and that is requiring more etch and deposition technology, and it tends to expand our SAM. What we’ve said is every technology node in DRAM, NAND, and in Foundry/Logic, our SAM grows if the technology moves forward. So, your question about DRAM is no different. We do anticipate and we said that we think we enter 2021 with a good setup for rising DRAM spending. As you pointed out, a couple of years of flattish DRAM spending where we've kind of been under growing long-term demand. And so, we combine increased spending with, we see as higher intensity due to these technology changes that require more etch and deposition equipment, we think it's a good setup for Lam going into 2021.

And then, Doug, on -- obviously, very strong gross margin performance by the company. And that's even still with the higher logistics and transport and freight-related cost due to COVID-19. Can you just give us an update here, and maybe give us a sense on how big that impact is to your gross margins either in the just reported September quarter or in the December quarter guide?

Yes, Harlan, I haven't quantified it, but it's noticeable. I mean, let me put it that way. I mean freight logistics spending is quite expensive right now simply because there's just not enough airfreight flying across the Pacific Ocean where a lot of our stuff comes and goes. But I haven't quantified it. Harlan, the right way -- maybe just thinking back longer-term to the financial model, but the right way to think about it is still the numbers that are embedded in there. Right now, when I think about the revenue levels we're at, we're trending a little bit below what might be in that model and it's because of the COVID inefficiencies, in particular, freight and logistics. I'm not going to quantify it for you, though, but that's how you should be thinking about it. And we had a really positive mix in September. We don't have quite as positive mix in December. So that's the commentary around sequential gross margin.

We'll go ahead and take our next question from John Pitzer with Credit Suisse. Please go ahead.

I guess, Tim, Doug, you talked about SMIC in the December quarter being a hit, but I was hoping you could quantify that. And as you do, kind of help us understand how China might trend as a percent of revenue in the December quarter. It's been well above trend. And I know you've talked about broad-based strength, but do you see that kind of well above trend representation in the December quarter as well?

Yes, John, I'm not going to quantify the large Chinese foundry impact to the guide. I think the numbers I've seen people suggest, percent of revenue, WFE, longer-term basis, the right way to kind of think about where that particular customer might have been and could continue to be if we are all in the industry able to get licenses. In any given quarter, it can be up or down as all customers are. So I'm not going to specifically quantify it in December, but I think you know roughly how big they are.

That's helpful. And I apologize for the follow-up, but you guys clearly understand the concern out there is, how much of the China strength is related to customers that are being worried about full bans going into China by the U.S. government. Tim, I'd like to get your kind of thoughts. In a worst-case scenario, if the U.S. were to ban equipment going into China, how much of the China CapEx in WFE today do you think would need to be reconstituted in other geographies to support demand? And how much of it do you think could be lost in just representative of kind of China building in anticipation of demand multiple years out as they go -- pursue their semiconductor -- domestic semiconductor strategy?

Well, I mean it's a very difficult question to answer from the standpoint that in many ways, what you just implied in the question was that some of that may be building in China in anticipation of demand they see several years out. We think that demand -- I mean, for all of the reasons that we talked about, whether it's -- I mean, it's just the digitization of the global economy, that's occurring everywhere. And so we think that demand remains. And so to your point of how much of it gets reconstituted, how much of it gets satisfied, I think China demand, global demand has to be satisfied by somebody. And so I think, ultimately, a lot of it gets reconstituted. And the only part that might not be is, what we have acknowledged, and I think most people recognize is as you're coming up the learning curve, there can be in the short-term some overspending as you're learning and you're building yield and you're gaining efficiencies. But even in the long run, that -- we've seen that play out over every region. And what ends up happening is that turns in ultimately to business -- for our installed base business, where we go back years later, and we're making that installed base productive. And so this industry is so efficient but I don't think there's ever really anything that gets lost, quite honestly. And that's -- but I mean, there's a lot of -- there were probably a lot of pieces to your question that require assumptions. But I think that it would cause some disruption, as we said, in the short-term. But in the long term, demand drivers and the need to supply semiconductors and semiconductors equipment to meet them doesn't fundamentally change in our view.

Yes. And maybe, John, I'd just add a couple of things, the way I think about it. When I look at the revenue in China for us, it's split fairly evenly between the multinational customer base and the local Chinese customer base. So to help you frame it a little bit, that multinational stuff, obviously, was a decision to put in a country that could have gone anywhere quite honestly. And then as Tim alluded to, a lot of the Chinese customers are relatively new in their process ramps, so maybe they're a little bit inefficient or somewhat inefficient. But at the end of the day, they're building capacity to support long-term demand that somebody else will step into over a period of time. So anyway hopefully that's helpful.

And we'll go ahead and take our next question from Timothy Arcuri with UBS. Please go ahead.

I had 2. I guess the first one, Doug, is on service. And I guess the question is, how much, if any, inventory stocking of spares, do you think is going on? I know you try to put controls around that. But it seems pretty clear how much service has taken off for the past 6 months that maybe that is actually happening. You've been pretty clear that you can't run the tool if you don't get the spares, so it wouldn't make any sense to pull the tool in. But we have heard that there is some communal stocking happening in China for parts and whatnot. So can you speak to how much of a factor that is? Do you actually see that happening?

Yes, Tim, it's hard to know, to be perfectly honest. One thing I looked at in anticipation of this question coming up is, from the beginning of the quarter to the end of the quarter, did any customer meaningfully increase their spares orders with us in China? And the answer to that was, no, not really. That doesn't mean that maybe they weren't planning to stock a little bit ahead. It would be pretty hard at times to know. But I don't see a big stocking going on in China for spares. That's maybe the way I'd summarize that. I don't know, Tim, if you think any differently about that.

No, I think that's fair. I mean, obviously, just as you see, even sometimes in our own numbers, is you're building for growth. I mean, there's no doubt, the inventories themselves, the number of parts that have to be stocked and maybe it’s what we’d call the safety stock level. I mean, those may rise. I mean when you're in the early days of a manufacturing fab, you’re always concerned about like the time to get another part shipped in. But as you really start working towards efficient mass production, you do that. So I think we have seen -- and clearly, we have seen that shipments have increased, but whether they're increasing more than the growth plans of the -- of those customers, a little bit more hard to say. And I'd say just across the board, there's a little bit of a -- everybody is focused on business resilience. But as we talk about things that may be structural, I think for quite a long time, and people are going to be looking at what do I have to do to ensure my business can run. And so I don't think those -- you see those immediately like turned on and off.

And then, Doug, I guess a follow-up just on the balance sheet. You did start to repo back up, $450 million is definitely a respectable number, but you still have $7 billion in cash. And I think in the past, you said maybe you did $4 billion but that's kind of the optimal cash. So you definitely have a lot of excess cash. So maybe can you update us there on your thoughts on what you're thinking with the excess cash? I think it seems a little harder that you'd be able to do M&A and semis to get some regions to improve that. So can you just talk to the excess cash level, Doug?

Yes, Tim, I specifically reiterated the 75% to 100% return to free cash flow as the company's planned objective. I don't know think of it, however, that's what we're planning to do. Now over the last couple of years, we've done more than that. We've done more than 100%. And your observation is right. We probably have a little more cash than we need sitting on the balance sheet right now. We'll be looking at that periodically over time. But I don't have anything new to tell you right now relative to any change in our plans or thinking.

And we'll go ahead and take our next question from Krish Sankar with Cowen & Company. Please go ahead.

I have two of them. First one for Tim. On the NAND side, when your customers go from 96 to 128 layers, as you move organically, the etch times went up, and which is a big positive for Lam. But going beyond 128 layers, if customers start stacking layers, is it a slight negative? What I'm trying to figure out is, is stacking neutral or negative for dep and etch intensity? And then I have a follow-up.

I mean the simple answer is no, SAM still grows under every scheme to build more layers. It translates into different parts. Again, I've talked about this where you kind of picked your battle whether you're trying to build ever taller stacks in one shot or you're trying to build efficient stacking. But simple answer is etch and dep intensity rises in either case. Just perhaps split differently with different applications.

And then a follow-up for Doug. Would you be willing to share how much of your service of CSBG revenues is from domestic China or overall China?

Not that I'm willing to share it, Krish, because off the top of my -- I'm not sure I know what the number is. The way to think about it over time is consistent with equipment shipment with a lag, right? And the way we've generally been talking about the business for us from a system standpoint in China is, it's been pretty evenly split between multinational customers and local China. And over time, the CSBG business kind of would get caught up to a similar footprint, if you will, maybe not immediately. But Krish, that's just off the cuff reaction to the question.

And we'll go ahead and take our next question from Vivek Arya with Bank of America. Please go ahead.

I was hoping if you could give us some directional view on the China versus non-China and the Foundry/Logic versus memory mix for the December quarter guidance?

You're asking, Vivek, about December specifically?

That's right. Just directionally how do you see those mix things trending in December?

Yes. I think China is going to remain strong in December is how I view it right now as we sit here today. And I think the broad-based set of customers in China that I tried to describe will continue to be what it looks like.

And on the Foundry/Logic versus memory mix?

Well, the large China foundry customer likely isn't going to get much from us, if anything, unless we get a license in December. So that will probably trend down a little bit in December.

Got it. And as my follow-up, I wanted to revisit this DRAM question. I understand DRAM sales are still below their peaks, but they are still back to the levels you had in the second half '18. How are you thinking about your DRAM growth over the next several quarters? What are the signs that you're looking for to say that now we are at a trough, and now we can get back to some normalized trend?

I mean, Vivek, what we look at is we run our own models of bit supply growth and do our best to try to understand inventory that's out there, what the customers are holding, what the customers’ customers are holding. What's going on with pricing? What's going on profitability? And as we look at all of those things, our view is, right now, the investment levels that are occurring in DRAM are generating supply growth below long-term demand growth. And at some point, that will need to get itself caught up. And we think it's sometime in 2021. I think it sets up to be a pretty decent year for DRAM in 2021 is as much as I can tell you right now. I don't know, Tim, if you want to add anything?

No. I think also just you referred back to like 2018, and I think that, again, for us, we look and there are -- across all semiconductor segments, I mean, significantly greater drivers and broadening of drivers we're seeing today. And we pointed out a couple of those on previous calls. But just even the difference in DRAM content in the high-end smartphones and the dramatic jump that takes from -- into the 5G phones. And then, of course, we talk about the buildout of data centers and everything else. It's -- there's a demand element to it. There's the supply element. And I think we just see it as a positive into 2021.

And we'll go ahead and take our next question from Toshiya Hari with Goldman Sachs. Please go ahead.

I had 2 as well. First one, I guess, is very much a follow-up to the last question on DRAM and NAND supply growth exiting the year. Doug, you just talked about your internal model. You’re suggesting that the supply growth exiting the year is below the long-term trend line as you see it. Is there any way you can give kind of quantitative color around that. For DRAM, are you looking at kind of 15% to 20%-ish supply growth exiting the year? In NAND, is it kind of around 30 or below 30%? And I guess related to that, you talked about your expectations for DRAM into 2021 being positive. Any directional guidance you can give on the NAND side?

Yes, Toshiya, those numbers you referenced probably are fairly consistent with what I think is the consensus view as well as our own models. So I don't have anything incremental to add there. Your second question, sorry, ask it again.

Yes, directional guidance on NAND into 2021, if any?

My view, I mean NAND is pretty decent right now. And I think it will be pretty decent next year. Again, based on our view of the industry inventory, investment plans, I think it will be a pretty decent year for '21 next year. We're not going to give you numbers on '21 yet. We'll do that in next quarter's earnings. But I think it sets up pretty well.

Got it. And then a quick follow-up. In terms of market share, you guys talked about 4 to 8 percentage points of share growth like kind of your 2023 target at your Analyst Day. If I take the midpoint of your December quarter guidance and make assumptions around your CSBG business, I think your systems business is going to be up close to 25-ish percent in calendar '20, so you're clearly gaining share. What sort of the outlook into next year based on wins that you have already, both on the memory side and logic and foundry side, do you think you can sustain this level of share growth momentum? Or could that accelerate? Could that slow down a little bit? Any color would be great.

We're certainly going to try. And I think that in our business -- we've described this in many ways, every quarter, we come in and we talk about wins and new applications. And I know it kind of starts to sound like we're a broken record here. But the reality is it takes a couple of years for those wins to start to translate into the numbers that you're starting to see now. And so if you go back and you kind of look at the old transcripts, you'll see us talking about pretty significant momentum that started really in the 2019 time frame. And it's been building through 2020, and that's what you're going to start seeing I think play out. As those wins at those future nodes start to roll in through high-volume manufacturing. I'd make the same caution we're extremely happy with Sense.i momentum right now as it's winning sort of those slots and sockets in future nodes. But I know the timing for those to then become the main driver of revenue and market share growth won't be until those nodes that are in development now and moving into pilot become high-volume nodes. But that's -- so I would say that we look back 2 years to our progress, and that's kind of what we're starting to see, and we look at wins we're making now. And that's our pipeline to hit the 2023, 2024 objectives. And I think we -- as we said, we feel we're on track and almost couldn't feel better about the strength of the product portfolio and the pipeline right now.

And we'll go ahead and take our next question from Joe Moore with Morgan Stanley. Please go ahead.

I wonder if we could get some additional color on the restrictions in China. When exactly did they kind of go into place. And just so I understand for modification if it happens again, what happens to product that's being installed on-site to product that's shipped on the way there that stuff fits in backlog? Are you still able to ship against that?

Maybe I'll make a couple of comments. And then Tim, you can add on. I mean the incremental I think that came out was really an application of a rule that was previously out there around military end use that basically said, if you’re enabling that, one of our customers is, you need a license. And so what ended up happening is, I guess, guidance, if you will, from the Department of Commerce that you need the license to ship to at least 1 customer, the foundry customer in China. I mean, that's really the only thing that was new, Joe. And so we're applying for license is basically what's going on. I don't know how long it's going to take to find out whether those license will be granted or won't. We're kind of in sort of uncharted territory, and we're waiting to see how it plays out. So timing, I don't know that I can help you much with.

Okay. And then in terms of the backlog and anything that might be assembled on site.

Generally speaking, when these rules come out, you get a little bit of a lead time, so you can adjust whatever is like in the very near term going on. But it's hard to know, quite honestly. So at this point, we are complying with all regulations that are out there relative to this 1 customer, which means we're delaying the shipment plan for the December quarter, basically it’s what's going on until we know more.

And we'll go ahead and take our next question from Blayne Curtis with Barclays Capital. Please go ahead.

I was just going to -- love a little more color on just the trailing edge strength. How much of a trigger that was. Obviously, we've heard about tightness and clearly seeing a rebound, but a lot of these end markets are kind of still down a bit. Kind of just your perspective, is the different mix, particularly in markets with higher content. And kind of just perspective, is this just a little bit of a catch-up? Or is it a more sustainable trend?

No. I think this -- I mean, at least from our view, I mean, I mentioned it was another record quarter for our business group that satisfies that demand. We've just seen tightness in this market and kind of a broadening of those activities quarter-by-quarter. So -- and if you go back and look, we've reported record quarters now for quite a number of [quarters]. So I think it's just tightness. It's difficult. In fact, we just had a very strangely, but a new product release, where we talked about we're leasing a product now for 200-millimeter photoresist strip. And so I think you can get a sense from that where we're going back and basically refreshing 200-millimeter products that the demand is out there, and it cannot be solved or served just by refurbishment of the existing base. It's -- the requirement is actually expanding beyond that.

Yes, Blayne, I mean, I know you know this market really well. I kind of think of the analogy IoT edge kind of devices that are out there, you know what's going on there. I mean, that's really what's going on with this part of our business as well. Back at our Investor Day in March, we suggested that we think WFE in this space quickly grow 2 times to 3 times faster than WFE broadly. And that's what's going on.

Got you. And then maybe as a follow-up, you mentioned that WFE would grow next year. You're not giving the specific guidance. You mentioned memory up, I didn't hear you say foundry. So I guess I'm just curious, obviously, you don't know what's going to go on with SMIC and licenses in China in general. But just kind of curious, with the strength of the trailing edge, is foundry going to be up next year as well, kind of the factors there?

Yes, Blayne, our normal practice at this point in the year is not to give specific numeric, here's what next year looks like. We'll do that a quarter from now. We're giving you a little bit of color that we think it's going to be a good year next year, but it's too soon for us to quantify. We just -- our practice is to wait until the December quarter earnings to give you that. And we will give it to you then.

And we'll go ahead and take our next question from Atif Malik with Citi. Please go ahead.

Doug, you have talked about a $10 billion domestic China WFE number in the past, and is that still the right number within the mid-50s WFE for the market?

Yes. Our view is still mid-high 50s from a WFE standpoint, in China, roughly $10 billion, plus or minus a little bit. We're 3 quarters of the way through the year. So if the 1 customer that everybody is thinking about right now isn't able to spend in the fourth quarter, we're still in that range.

Okay. And as a follow-up, has the backlog normalized due to COVID-19 impact in the March quarter and now fully reflected in your Q4 revenue guide? Or you still have some carryover?

No, Atif, we're pretty much caught up at this point.

And we'll go ahead and take our next question from Sidney Ho with Deutsche Bank. Please go ahead.

My first question is going back to China, given the strength you've seen last quarter, are there any risk of customers pulling in purchases? I think you addressed the spare part side earlier. But the question is not just from the 1 foundry customer, but also maybe other customers on the memory side as well.

Well, I guess you addressed it, is there a risk? Do you mean backward-looking risk in the September, the risk that pulling occurred? I think Doug kind of answered that, which is we really haven't seen or felt anything that feels out of the ordinary relative to the growth plans for these customers. Going forward, I think, again, in many ways, you see us guiding to yet another record for the company. And I don't think that we'll be -- I don't think that any of that right now factors in what we would, again, think is abnormal pull-in activity.

Okay. I think you guys were talking about spare parts earlier, but I guess the system -- new system itself…

So I mean, no, we're…

I think the question maybe was about spare parts, but it's really more of -- I think it's a broader statement.

Yes. I agree.

Okay. Maybe my follow-up question is on Intel. I think last quarter, you guys pretty much said this, there's no impact. It doesn't matter who makes the chips. But on the memory side, now that Intel sold the business -- NAND business to Hynix, given that they have very different architecture, do you think there will be a net impact for you guys going forward?

Well, hard to know. That's a pretty recent announcement, and it would be a little bit of speculation. I mean, Sidney, long-term, the way I think about this is, at the end of the day, demand is what matters, right? Our customers are putting wafer capacity in place to supply demand. And things can get pulled in, pushed out a little bit on the margin. But at the end of the day, when I think about where I think the industry heads, supply and demand have to be in relative equilibrium, over the medium or longer term. And whether that means we have 5 customers in NAND or 3, it largely doesn't matter. They're going to invest to satisfy demand in my mind.

Yes. And the -- question was, is it all targeted towards that strength. I mean, we basically have talked, I think in the past. We're strong across all flavors of 3D NAND.

We'll go ahead and take our next question from Joe Quatrochi with Wells Fargo. Please go ahead.

On the NAND, I was curious, within your bit supply growth model or expectations, how do you think about the growth from no transitions or technology transitions in terms of, if bit demand is closer to 30% next year and versus kind of a long-term of high 30%, do you think the installed base needs to grow to support that?

In any given year, Joe, when we look at it, there's always a blend of both. It's always in the best interest of the customer to do the node conversions first because it's a very cost-effective way to do it. And then generally, that means you lose wafer capacity and it needs to get topped up a little bit. In any 1 year, the mix is different 1 year to the next but it's always a blend.

Okay. That's helpful. And then just -- I thought your comments in the prepared remarks around support engagements being a remote. That was interesting, obviously, with COVID. And so I was curious, how do you see that trending over the next few years. And maybe what percentage of engagements are remote now? And maybe how do we think about the cost savings potential there?

Yes. It's -- well, I guess what I would say is we featured the Equipment Intelligence solutions. You imagine if we're launching Sense.i designed around Equipment Intelligence, we started that activity long before COVID was ever even something we could imagine. So we feel very fortunate now that we're driving that aggressively. And it really is designed to do things that remove the need for people to be physically located at the tool in order to troubleshoot and repair the tools. And so we have seen -- I mentioned a 6x increase in remote support engagements year-over-year. A lot of that is because our engagement with customers, there's kind of like not many other choices at this point to bring the kind of expertise you need to the tool. And I think that what -- just as we're seeing with work from home and other things, a lot of that will remain structural. It is -- it does save money for the customers by allowing us to repair the tools and get them back into production more quickly. And it saves money for Lam because we don't have to deploy as many people flying all over the world trying to service these tools. So I think a lot of that, I hope and I believe, will be structural and long lasting.

Operator, we have time for one more question please.

Perfect. We'll go ahead and take our last question from Weston Twigg with KeyBanc Capital Markets. Please go ahead.

Quick 2 questions. First, advanced packaging, you talked about it in the opening remarks. Can you help quantify what that is as a percent of systems revenue? Or sort of how relevant it is to the overall top line?

You know, Wes, right now, it's small, but with nice growth trajectory. And we're excited about what the future looks like. It's not huge right now. But when you listen to the industry and our customers talk about it over time, it's clearly part of their road map to drive Moore's Law forward. So we're excited about it. It's not huge now. We hope it will be over time.

I think, though, it also is -- Wes, maybe you've been around a long time. So you recognize the SABRE name point. And the point there is, in many cases, these are -- I mentioned this is about leveraging a lot of the expertise we've already built for other applications into new areas where we can gain high share. And it doesn't require in those cases for those markets to be quite so big to start to have an impact. So SABRE 3D, very, very strong position, very long track record. A lot of that R&D already kind of being done for larger markets; Syndion, same thing in terms of very high, very strong market position. And then, as Doug pointed out, what we're really trying to say, we have those positions, and we actually see the market coming to us as more of these integration schemes continue to go 3D. So we highlighted it just as it's one other example of 3D helping drive incremental growth for the company.

I see. Okay. That makes a lot of sense. And then the other question I had was just the U.S., it was remarkably low in terms of revenue contribution last quarter. I was wondering if you could offer any commentary on that, if that's a trend that you see or it's just an abnormally low quarter?

There's not a lot of fabs in the U.S. taking equipment. I mean that's what's going on. I mean this is a [shift key] statement. And most of our customers' fabs are outside the United States, Wes, you know that.

Yes. I guess, it had dropped a lot quarter-over-quarter as well. So it seems like the investment is declining. And I don't know if that's a sustainable trend and it could be, but that's the commentary I was looking for.

No. It's just -- you know how this works. Equipment can be lumpy to any one fab that come one quarter and then it needs to ramp. And it's lumpiness, but you know the fabs are in the U.S., and that's what's going on. It's just timing.

And that does conclude today's question-and-answer session. I'd like to turn the call back over to today's speakers for any additional or closing remarks.

No more closing remarks. Thank you, everyone, for joining today. We appreciate it.

Once again, this does conclude today's conference. We do appreciate your participation. You may now disconnect your phone lines.
