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.

    How many years we got skylake refresh? AMD still make good improvement, not every year, but at least on 2, and Zen4 is expected to delivery 25-30% ipc imrpovement. Reply

    Yeah they were making 20-25% gains per gen and the moment they passed intel the prices started going up, in the 6 core's case, 90% in a single gen for that 20% uplift.

    Never forget, the 3600 was a $169 product replaced with a $299 product. If you were a budget builder, go pound sand and buy intel.

    No, the 3600 launched at $199. It wasn't replaced until the 5600, which recently launched at... wait for it... $199!

    The 3600X launched at $249 and the 5600X launched at $299.

    As @Qasar, points out, that launched in Nov 2020, when demand for CPUs was abnormally high and Intel was still pushing Skylake cores on 14 nm. So, the $50 price increase was understandable, if unpalatable.

    You're making at least two errors, here. You're equating 6-core with 6-core, regardless of positioning, and you're comparing the discounted *old* model against pricing of the new model. 3600 didn't *launch* at $169.

    We could just blame supply problems & demand spikes on AMD and pat ourselves on the back for our moral outrage, but if you want more insight into *why* the prices shifted, then you can't ignore how the context changed.

    The Zen 3 product stack has been waiting for demand to slacken. AMD could have released these chips sooner, but they'd have only been cutting off profits for themselves.

    We don't have to /like/ it as buyers, but it's a cold calculus, and if we want AMD to survive as a competitor then some number of decisions like this will have to be made.

    I'm not sure about that. Zen 4 needs TSMC's N5 to be sufficiently mature (not to mention capacity) and DDR5 to have good availability. AMD should've wanted to launch it in Q1 of this year, especially if you consider all the discounting they're doing on the Ryzen 5000 product stack.

    > AMD could have released these chips sooner

    So, I reject the assertion that AMD simply didn't *want* to launch Zen 4 any sooner than they are. I think they're getting it out the door as soon as they reasonably could.

    Isnt it funny that it just so happens the demand slackens as SOON as intel's alderlake goes on sale? Almost like that's a massive cope.

    No, it's perfectly logical. Alder lake is much more competitive against Zen 3 than either generation before it. Of course that's going to steal some of Zen 3's demand! We'd be fools to pretend otherwise.

    You're so concerned with competition among CPU makers, but what about ASML? In particular, their exclusive partnership with Intel on high-NA (as in aperture -- not sodium!) is a little troubling.

    > it's still better than having Intel be burned so badly that
    > the investors chose to sell off their foundry business

    I still think that would be for the best. I'm glad Intel is starting to treat it more as a separate business, since that will ideally be the eventual outcome.

    "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"
    That does not mean that they will reach risk production as expected, or "real" production numbers as expected. It means that some hard problems were solved, and some other hard problems remain.
    As for the additional space needed... improved processes usually take longer (or much longer) per wafer, and (due to the increase in transistor counts) the number of processors per wafer didn't increase much.
