350 nm is massive and ancient relative to new processes, but the name of a new process stopped physically meaning anything a while ago. for instance, the 3 nm process smallest distance between traces is only 24 nm.

now the industry just names a new process when enough techniques for improving performance (without much actual size difference) exist.

I think this youtuber might have achieved similar nm with his DIY setup, but I don't remember. He's using a different process though.

breaking taps is very impressive, but sam zeloof made it quite a bit further, he made his own packaged IC. now he runs a startup called atomic semi, that is trying to use electron beam lithography for prototyping.
