TSMC's R&D boss addresses 40-nm yields, high-k, litho

I saw your nickname from the search page, and I knew what you'd post :D
Guess what... MSI lightning = still remain to be seen, and if the info regarding the amount of cards available for the launch is true, it's going to be a bigger joke than Fermi's delay :down:

Regardless of the AMD vs nVIDIA, you do realize that there's a huge difference in producing Evergreen chips ( IRL we should only count the big ones, fully fledged XT ) and Fermi.

I think TSMC "fixed" their 40nm tech process more times than Nvidia announced that Fermi is "Coming soon (tm)!" :rofl:

NVIDIA didn't do that breaking to many rules and pushing TSMC's manufacturing capabilities to the limit.

That would be the issues with vias degrading (which they got around by using double vias, I think), and other things that were difficult with TSMC's 40nm process, right?

great blog with lots of pictures about this topic:

interesting but no real news... thx though :toast:
