Ah, not to worry, even professionally it’s very common to buy your wafers. I am on mobile data right now so I’ll check out those videos later!
Basically, every single machine that needs a vacuum chamber - so almost all non-wet processes, like physical/chemical vapor deposition, reactive ion etching, scanning electron microscopy (although a good optical microscope will do if you’re not at the nano scale… Which is almost certainly the case if you’re doing things at home).
Honestly maybe I’m just too used to the lab setting and am underestimating how much you can actually do without vacuum processing. I’ll take a look later: this all looked so out of the reach of an ordinary person that I never even considered following content creators who do this. Thank you!
Man, I think I’d prefer that outcome. Getting laid is easy compared to finding fun people to game with
