Yeah, I feel like I'm missing something here, but in the other thread the guy says you can get everything you need for 5nm from Alibaba, but afaik to get to such small transistors (5nm) you need EUV lithography, and is there anyone other than ASML manufacturing those machines?



"but in the other thread the guy says you can get everything you need for 5nm from Alibaba"

You sure can if all you want to print is one 100mm wafer per month.

Multi-beam tools that can reduce that to a wafer (or reticle) every few hours are real fscking expensive.


Boutique ASICS?


Lithography isn't the only way to construct transistor, it is possible to to construct much smaller transistors using alternative tech. Not in scale, though


You can make a mold for low volume stuff.


Who would be the customer? Or would this be for research purposes?
