Sam Zeloof also created his own transistors, then founded AtomicSemi/fab2: https://youtube.com/watch?v=IS5ycm7VfXg

inspired by Jeri Ellsworth, who also documented hers on Youtube: https://youtube.com/playlist?list=PL5DCEA197C1C07A2D

Sam Zeloof's new company is a serious business. He went from studying electrical engineering at CMU and doing semiconductor fabrication as a hobby, to running a well funded team to produce equipment for mini-fabs.

It is actually a great example which shows the difference between cobbling something together in a garage, to produce a one-off demonstration, and having a mini-fab which is capable of delivering the results reliably. The difference in the required effort is many orders of magnitude.

The "RAM in a shed" guy started with a Ph.D. in semiconductor technology, and was running a company before he made the improvised lab at home and started to make videos about it. He uses the lab to test some of the steps for the specialty devices which he invents.

Saw Jeri demo some of her early transistors, it was one of the most inspiring things seen in a hackerspace… 15 years ago now? Sheesh. Glad to see AtomicSemi/fab2 in existence, that is a relief. We simply have to get desk-side fabrication happening, faster, imho ..

Also seems to mostly go off of Hacker Fab (https://docs.hackerfab.org/home)
