Man makes silicon chips in his garage fab

My first thought was about reading the Berkeley semi fab class lab manual. It started out with a long chapter on safety in the clean room, explaining that the purpose of the bunny suit is to keep the chips clean, not to protect you from that cyanide and hydrofluoric acid. And that the buddy system was enforced for the above reasons.
This looks like it’s small enough scale (a dozen chips in a batch) to be manageable on the safety end. Still, don’t go in there without knowing exactly what you’re doing and being highly alert.
