I’ve been hearing a lot about silicon water growth method, does anyone have more info on that?

the most fundamental silicon etching is nitride etching. For this Silicon Nitride (a compound of silicon and nitrogen) is used as masking material and is the most thermodynamically stable. A thin film of the Si3N4 is placed on the silicon wafer and hot phosphoric is poured onto it to perform the etching process. This is performed in a nitride etch bath with a hot phosphoric acid trip at 180° C.
