I was looking for how he managed the clean room or did he not go too small. Found the answer in the IEEE article shared by another commenter (he didn't go below 10 micron tech node).
But now I have a follow up question, if getting a clean room is obviously harder, isn't "clean box" more doable? E.g., if you line up a bunch of tables, and put a long box on top that acts like a poor man's assembly line. The insides of that box are only accessible through gloves that are attached to holes on the sides of the box, and plenty of glass windows to look inside (kinda like the box in movie 'Life'). How cost effective and feasible (i.e., gets the job done) would that be compared to a clean room? maybe you could go sub-micron with it if not sub-100nm.

- sanxiyn 8y ago"clean box" is already used. It's called FOUP: https://en.wikipedia.org/wiki/FOUP https://en.wikipedia.org/wiki/FOUP
- sonium 8y agoAlso if you don't really care about yield, many things are not that critical. I did a PhD in semi-conductor physics, and most processes for silicon are actually surprisingly robust (compared to processes of any other material). Also many things are just done the way because people know it worked before, which does not mean you can't use less fancy equipment and it would still work.
