Well there are claims that Huawei is aiming for 3nm with GAA with tape out next year See Here.
I think we shouldn’t forget that the nm numbers really are just that: Numbers. They don’t correspond to any specific measurements and can be chosen more or less arbitrarily. So 6nm for example might just be a slightly refined 7nm node.
Another thing is power efficiency and yields. If they get 4060 performance at terrible yields and with massive power draw then it is very different to getting there at similar parameters as Nvidia.
If China does end up cracking EUV by themselves it would indeed be massive. It’s arguably one of the most complex things mankind has ever done. But there are so many factors to get right that tbh I don’t see it happening any time soon.
Isn’t GAA one of the most advanced types?
If they can really do this next year, there is no doubt China must have their own EUV lights.
So 6nm for example might just be a slightly refined 7nm node.
Absolutely true but AFAIK SMIC usually make their numbers comparable to TSMC. Even Intel changed their numbering to follow TSMC, and SAMSUNG and TSMC have always been close in their numbering.
We will have to see if the process is actually good, but I have little doubt that China will become competitive in EUV within 5 years. But if they have it already next year, that will be very fast.
GAA is the next evolution of transistor architecture from FinFET, but as far as I know has no direct link to smaller process nodes. In that (to my understanding) it doesn’t require small nodes and could be used just as easily in larger ones. It’s just that it is more difficult so until now there were other easier ways to make progress. However with new nodes getting more expensive and giving less scaling gaa and other things like backside power delivery are being pursued.

So not only do you expect China to have a working domestically produced EUV machine within 5 years, but a competitive one? Or possibly even next year?
Next year is just pure fantasy that I don’t think even the most optimistic would assume. If they were anywhere close to that we would already know. They’d have shown a working prototype by now.
Euv is crazy difficult and you not only the result of a single company ASML, but many highly specialized companies that are leaders in their respective fields and all over the world like e.g. Zeiss for for the lenses. So for China to replicate it domestically they’d need to copy the whole supply chain. Which is orders of magnitude more difficult than what they’ve done in other industries like electric vehicles or solar panels.
Imo if they have a working prototype of a complete EUV machine within this decade it would already be impressive. But that would still be far off from mass production or wherever the industry is by then (Intel is currently trialing high na EUV). Also for reference Wikipedia says ASML had their first prototype in 2006 and we know how long it took to being that to mass production. China as a second mover might have an edge that speed things up, but just knowing how it works in theory isn’t enough and there are o shortcuts.
But maybe they also pursue another technique such as nano imprint (like canon) to achieve smaller nodes. Maybe that would be easier to replicate without existing global supply chains.
AFAIK Canon has a process (nano imprint) that competes with EUV too, maybe not as advanced as ASML.
When I say China will have a competitive EUV system within 5 years, I don’t mean competitive in how advanced it is compared to the best ASML has to offer like the new NA process TSMC hasn’t even decided to buy yet.
But an EUV that allows a production process that will be competitive down to just below 2nm. Meaning competitive with the EUV process TSMC is currently using.
Depending on how much China is investing in this, they could be working on different processes in parallel.
Obviously anything as hard as this with a 5 year time span is very uncertain, we recently saw how bad things went for Intel with their 10nm process, being both multiple years delayed, and on top of that pretty bad when they finally announced it was ready.
As I stated next year would be very fast, but in reality we don’t know how close they are. Your claim that they would advertise it is speculation. What would be the purpose of that?
China is already competitive in 8 out of 10 key industries, and since China is prevented from even using western parts for chip making or even just buying the chips, they are pulling ressources to catch up. China will do this because they have massive talent mass and ressources, and because they have to.
Your claim that they would advertise it is speculation. What would be the purpose of that?
To advertise that they can? In return what would be the purpose to hide it?
They do seem to make their advancements at least somewhat public, e.g. with their recent progress with a EUV light source.
I am probably on the pessimistic side and you maybe on the optimistic, so the reality will likely end up being somewhere in between (but only time will tell).
China will do this because they have massive talent mass and ressources, and because they have to.
Well it also was developed in the west by a large amount of talent and resources and still took a lot of time. But you are absolutely right that their hand is being forced.
Restricting exports like this imo was a huge mistake, imo especially in regard to duv. In the end it might have achieved some damage in the short/medium term, but that wasn’t anything the us could capitalize on and it also directly hurt ASMLs profits (meaning less resources to advance). And regardless how the timeline ends up looking on the end (be it closer to your or my prediction), physics are the same everywhere so that can’t be restricted and they will eventually be able to figure it out.
To avoid further retaliations from USA that might prevent their progress.
And to not disclose industry secrets.

True, I’m an optimist on their behalf, because China has done such impressive progress already, but I also know this is way harder than sending a man to the moon.
I agree 100% about restricting the tech is a huge mistake, and yes physics are indeed the same everywhere.
Hopefully when China figures it out, consumers everywhere will benefit. The Political implications however, is an open question.
