TSMC: 3nm in 2021, and 5nm has satisfactory yields

Don't think he's triggered - was intending it as more of a "strain" on 14nm.

Congratulations to TSMC.

Now, I don't know which of their numerous fabs, nearly all of which are located in Taiwan, are producing these 5nm products, but I'd certainly like to see them duplicate their production facilities in at least one other location in the World. I've been of this opinion for quite awhile. Years.

Having all these eggs in (mostly) a single basket is problematic in terms of a possible natural disaster; it is an island, after all. Recall the impact of the flooding in Thailand years back had on hard drive production.

Aside from Mother Nature, it also seems a little too possible for some miscreant human entity to recognize just how much, in general, technology is centered on TSMC, and attempt, "That's a really nice fab facility you have there. Be a shame if something happened to it.." Or, some variation of that.

I mean, these are fragile, delicate operations. We've all seen interior photos of wafer processing facilities. I likely have enough crud under just the front seat of my car to trash every fab on the entire island, six times over. Any sort of determined human "unrest" would likely be apocalyptic.

Even in the absence of current events, it just seems like a good strategy to have something like a major force in the semiconductor production business not only have their facilities scattered, but replicated. And, yes, I've no doubt whatsoever who would ultimately underwrite the cost of this replication.


actually i suspect this is part of a national strategy by R.O.C. (Taipei). there is no nation as dependent on these fabs (and factories i.e. mobos) as the USA, upon whom the Taiwanese rely on for security. it's just a short boat ride to the mainland of China, so being the object of desire (for China) and a security partner of the USA is all part of the delicate dance they have to do to stay free. of course, with the unrest in Hong Kong, all of the lies of "one country, two systems" have been laid bare. even so by being the nicest "China shop" around does help to avoid bulls.

obtw....
my info on TSMC came from an INTERVIEW done with EETimes (electronic engineering times)
the most highly regarded industry site.

so. just. suck. it.

My problem isn't that you're right or wrong, for all I know you work for these companies and everything you're posting is 100% accurate - my problem is that you do this. You make a statement like "AMD is getting it's own dedicated node that's better than 5nm according to TSMC" - which I cannot find a source for at all - in fact the only thing I can find on this claim is what I posted (chinese rumor, not from TSMC). You don't post your source. Then when I call you out on it, you again say it's from a place but don't post the source.

I googled around looking for an EETimes interview and I cannot find one that backs the 5nm claim up. So I thought maybe you're talking about the Nvidia claim on Samsung 7nm - so I googled that too:

https://www.tomshardware.com/news/samsung-nvidia-7nm-ampere-tsmc,39583.html

Which points to this EETimes article as a source:

https://www.eetimes.com/intel-says-euv-ready-challenging/

Which doesn't even mention Nvidia.

So please link it so we can read it - in fact please link both. Otherwise I'm going to assume you're just doing the same thing you've done in multiple threads before this - making up sources. In which case I go back to my original statement, you're pulling it out of your ass -- and for all I know your ass is a treasure trove of good information -- but it's still coming from there.

It's just he @Denial either misunderstood or didn't phrase this correctly. TSMC makes a new node it is for low power chips which is why Apple is always one node ahead of AMD since Apple gets on siad new node due to low power iPhone/iPad chips. Then TSMC takes said new node and tweaks it for high power chips. This usually takes about a year give or take a few months. Today AMD is a big client but obviously TSMC does not make a higher power process just for AMD.
