Intel for the last few years has been undergoing a major period of manufacturing expansion for the company. While the more recent announcements of new facilities in Ohio and Germany have understandably taken a lot of the spotlight – especially given their importance to Intel’s Foundry Services plans – Intel has been working even longer on expanding their existing facilities for their own use. The company’s development of next-generation EUV and Gate-All-Around-style transistors (RibbonFET) not only requires creating and refining the underlying technology, but it also just flat out requires more space. A lot of it.

To that end, Intel today is holding a grand opening in Oregon for the Mod3 expansion of D1X, the company’s primary development fab. The expansion, first announced back in 2019, is the third such mod (module) and second expansion for Intel’s main dev fab to be built since D1X’s initial construction in 2010. And in keeping with tradition for Intel fab launches and expansions, the company is making something of an event of it, including bringing Oregon’s governor out to show off their $3 Billion investment.

But fanfare aside, the latest mod for the fab is a genuinely important one for Intel: not only does it add a further 270,000 square feet of clean room space to the facility – expanding D1X by about 20% – but it’s the only fab module that’s big enough to support the High Numerical Aperture (High NA) EUV tool that Intel will be using starting with its 18A process. ASML’s forthcoming TWINSCAN EXE:5200 EUV tool is designed to be their most powerful yet, but it’s also quite a bit larger than the NXE 3000 series EUV tools Intel is using for their first generation EUV processes (Intel 4/Intel 3). It’s so big that D1X’s ceiling is too low to fit the machine, never mind the floor supporting its weight.

As a result, Mod3 has been built, in no small part, to fit this massive machine. Intel isn’t expecting to take delivery of the machine for a couple more years, but they had to start preparations years in advance just to get to this point.

Meanwhile, although D1X-Mod3 is only being officially declared open today, Intel has already been moving critical tools into Mod3 since last August. Consequently, today’s opening is something of a ceremonial launch for the mod, as parts of it are already setup (if not already in use). Still, even with that head start, according to Intel the company expects to be moving in tools for another year, especially as they bring in the remaining, lower-priority tools.

Coincidentally, our own Dr. Ian Cutress had a chance to see D1X in all of its glory late last year, when he toured the facility. At the time Intel was already in the final stages of finishing the Mod3 expansion, as well as bringing up EUV machines as part of the development of the Intel 4 and Intel 3 process nodes, Intel’s first EUV nodes. So for more information on D1X and what goes on there, be sure to check out that article.

Finally, along with formally opening the Mod3 expansion, Intel today is also using the opportunity to rename the 450-acre campus that D1X sits on. Intel’s Ronler Acres campus has been the center of Intel’s fab R&D efforts for decades, and along with D1X, also houses Intel’s older D1 development fabs, such as D1B, D1C, and D1D. So, in reflection of all of the important R&D that goes on at the site, Intel is renaming it after co-founder Gordon Moore, one of the instrumental figures behind the development of Intel’s earliest technologies. The newly renamed campus will now go by Gordon Moore Park at Ronler Acres, or Gordon Moore Park for short. And despite the many (many) things that have been named after Moore over the years, from laws and buildings to awards and medals, this is the largest thing named after Moore (yet), as it’s the first time a whole campus has been named after the luminary.

Intel Roadmap Update: Intel 18A Moved Up to H2 2024

Alongside briefing the press about the D1X-Mod3 opening, Intel also used their latest press event to get everyone up to speed on the latest updates on Intel’s development roadmap. Strictly speaking, nothing here is new – all of this was first announced during Intel’s 2022 Investor Meeting back in February. However this is the first time Intel has engaged the technical press, rather than investors, on the current state of its development efforts.

The big news here is that Intel is formally moving up the start date for manufacturing on the Intel 18A node. Intel’s second-generation “angstrom” node was originally expected in 2025; but now the company is bumping that up by half a year, to the second half of 2024.

As a result, Intel’s roadmap now looks like this:

With the company already gearing up for its first EUV process, Intel 4, later this year, Intel’s roadmap starts looking very compressed beginning in the second half of 2023. The second half of that year will see Intel 3 go into production, which is Intel’s enhanced EUV process. Meanwhile, potentially as soon as 6 months after that, Intel 20A goes into production. 20A is Intel’s first “angstrom” node, which incorporates their gate-all-around-style “RibbonFET” FinFets, as well as PowerVias.

But, if all goes according to plan, 20A will seemingly be a relatively short-lived node due to the movement of 18A. Intel’s second-generation angstrom node, which will incorporate an updated ribbon design and other improvements to Intel’s GAA manufacturing technology. Since 18A remains the farthest node out on Intel’s manufacturing roadmaps, the company is remaining relatively mum on everything new that 18A will entail, but it remains the point where Intel plans to re-establish unquestioned leadership of the chip making industry.

According to Intel, 18A development has been moving so well that the company’s R&D operations are now on or ahead of all of their development milestones, giving the company confidence that they can begin manufacturing products based on the process node in late 2024, instead of 2025 as first planned.

One consequence of bringing in 18A, however, is that it means Intel is now definitely going into initial production of 18A without all of their High NA machines. 18A remains the process node where High NA machines will debut, but as the TWINSCAN EXE 5200 is still not expected to be in place until 2025, that means Intel will now have to use their existing 3000 series machines to kickstart 18A production. Until this latest development, Intel had been presenting High NA machines and 18A as being tied at the hip, so whether that was always the actual case or not, now that is clearly not the case.

What that means for 18A production, in turns, remains to be seen. Since Intel can use their normal (non-HA) machines for 18A, then presumably the biggest advantages of the High NA machines were throughput, allowing Intel to process wafers with little (or not) multi-patterning thanks to High NA’s greater accuracy. Seemingly, the most likely outcome is that Intel will be able to produce 18A in 2024, and maybe even in decent volumes, but that they won’t be able to go into Intel-scale high volume manufacturing until the first High NA machine is available in 2025.

And, as always, it should be noted that Intel’s manufacturing roadmap dates are the earliest dates that a new process node goes into production, not the date that hardware based on the technology hits the shelves. So even if 18A launches in H2’24 as it’s now scheduled, it could very well be a few months into 2025 before the first products are in customer hands, especially if Intel launches in the later part of that window. All of which, given the large size of these launch windows and Intel’s own history, is a likely bet, as Intel has rarely launched new products/technologies early in a release window.

Finally, Intel’s development briefing also included confirmation that Intel is employing a purely internal “test risk reduction” node as part of their development process for their PowerVia technology. The purpose of the test node is to decouple the full risk of 20A by allowing Intel to develop and test PowerVias separately from RibbonFETs. In this case, the test node uses Intel’s well-established FinFET technology on the front-end, while employing a test version of PowerVia on the backend. No such node has been announced for RibbonFETs, but even if one doesn’t exist, not having to debug first-generation PowerVia on 20A alongside the RibbonFETs is still a simplification of the process, as it allows Intel to pursue both elements semi-independently, and learn from both of them in the process.

This is a significant change from how Intel has developed major new manufacturing nodes in the past, and even they are the first to admit as such. Intel’s 10nm problems were caused in large part by bundling too many technology changes together all at once, combined with a very aggressive reduction in feature size. Separating these things into smaller, more frequent manufacturing node updates was one way Intel is mitigating this risk in the future. And now with an internal test node for PowerVia development, they’re aiming to do even more risk mitigation in order to be able to roll out both RibbonFETs and PowerVia together in the first half of 2024 as part of Intel 20A.

    Well, that's a form of spam I haven't seen.
  • thestryker - Monday, April 11, 2022 - link

    The fab business being spun off is something some investors were already calling for so I think it's fair to say this is far more good than bad.

    AMD seems to be in a pretty solid position, even against SPR, and they've been making a lot of big moves so as long as none of it blows up I think they're good even with the imminent Intel rebound. It seems like each company is carving out their own priorities in the high profit sectors, and given production limitations (see TR Pro 5xxx supply issues) I think it'll be a few years before they're stomping on each other's toes again.
  • JayNor - Monday, April 11, 2022 - link

    AMD has no announced CPU with HBM in package, as already sampled on SPR-HBM.
  • mode_13h - Tuesday, April 12, 2022 - link

    Yes, but 3D cache puts a big dent in HBM's advantage (for some workloads).

    Has Intel even announced the programming model supported by SPR-HBM? Other than using it as L4 cache, I think it's not going to see a lot of use for the first year or so, while software support begins to ramp up for it. I see SPR-HBM as a software development vehicle for hierarchical memory, more than anything else. Sure, there will be some niche applications that benefit quite nicely from it.
  • thestryker - Tuesday, April 12, 2022 - link

    I don't believe they have announced the programming model, and the first chunk of them are going straight to HPC from what I've been able to find out. I'd imagine these will be the last SPR models to hit the market if they do at all.
  • whatthe123 - Wednesday, April 13, 2022 - link

    the hbm is probably on there for AVX512/AMX throughput in things like machine learning, not really displaced by milan-x. it'll end up competing with genoa.
  • mode_13h - Wednesday, April 13, 2022 - link

    > hbm is probably on there for AVX512/AMX throughput in things like machine learning

    Agreed. AMX / deep learning will need a lot of memory bandwidth. However, I think that's only part of the story.

    > it'll end up competing with genoa.

    Presumably, there'll be a Genoa-X, which will help against the case where Sapphire Rapids is simply using HBM as L4 cache.

    'Intel seems to have gotten it's shit together"

    Seems is the operative word. I'm sure Intel will have a node CALLED 18A. And they will ship something on it in 2023Q3. But will it actually be a significant change from the earlier node? And will the item shipped be of any relevance?

    intel Arc is an interesting test case for the supposedly new, supposedly honest Intel.
    That was going to ship Q1 2022. And, supposedly, in theory, it shipped, possibly, somewhere in the world, on March 30 which I guess is technically Q1 2022.
    But can you actually buy one? And if you could, would you want to?

    Now apply that same outcome to this process roadmap/fantasy...
  • eek2121 - Monday, April 11, 2022 - link

    Whatever it may be CALLED, it will be competitive with a similar TSMC offering. The whole reason they renamed things in the first place was because they were the only ones adhering to such tight standards. 'Intel 7' is quite similar to TSMC N7, and Intel 4 is expected to be better than the TSMC '4nm' equivalent.

    Now that they are getting their process issues straightened out, they need to improve their Core design to address power efficiency concerns.200+W for a CPU is NOT cool.
  • michael2k - Tuesday, April 12, 2022 - link

    They renamed it as a marketing exercise. If Intel's 10nm Enhanced SuperFin (it’s also been called 10nm+++ and 10nm++) was a bear to communicate.

    Also if it were competitive with TSMC N7 there wouldn't be a discussion about their competitiveness. Intel 7 has been in production since fall 2020; Apple was using TSMC N7 in fall 2018, two years earlier.

    Now if you're saying Intel has finally caught up to N7P and that later this year they will catch up to N5, and finally be current with TSMC's N4 by next year... you're guessing as much as anyone else.
