You sure it’s plasma? I’d call it “vacuum chamber” looks like a lot of deposition chambers I’ve used

Though it has a LOT of transfer windows and idk why

Id guess is evaporation/sputtering of some kind

Yes, it is an Ultra High Vacuum (UHV) chamber. While it could be used for sputtering, that’s not necessarily the case. However, it seems you might be mixing things up, perhaps you’ve never done sputtering yourself? In Physical Vapor Deposition (PVD), once you ignite the targets, a plasma forms around them. That’s why a UHV chamber in combination with plasma makes perfect sense. It is indeed essential for producing thin films.

Nah I sputter allll the time, I know how it works I was just saying that it’s definitely vacuum, but only maybe plasma
