There are some great services out there for people who want their designs made at that level. Speaking as someone who has worked in fabs - there are so many ways it can go wrong and so many ways you could kill/poison/burn/electrocute yourself if you tried to do it yourself. Your lithography would probably need a lot of tweaking too!

Yeah, I imagine it's take some kind of breakthrough technology vastly different to the current state of the art.

If it were to happen I don't think it'd look like an at-home-version of the present industrial process.
