Damn, he's got a lot of equipment though. I was hoping I could just setup a jig with 2x4s and melt sand with a blowtorch

Most of it isn't strictly necessary. Like, he has sputtering equipment for making layers that can't be chemically deposited for example. The one where he makes a MOSFET on camera involves just spin coating with tape and some random motor, a little tube furnace to bake impurities in and chemical etching IIRC.

He uses commercially available blank wafers; you'd need a small arc furnace (or at least a blast furnace and patience when your product is mostly iron) to make silicon from sand and something resembling a meth lab to clean it (and then you'd grow and cut your wafer, but that could be done on a desk I'm sure).
