The formation of aluminum fluoride layers on the inner part of plasma reactor walls is known to be a serious issue for plasma etching processes: it causes process drifts and particle generation. AlF x coatings are formed on the reactor walls as soon as the Al 2 O 3 reactor walls are exposed to fluorine (F)-based plasmas. Web• Hot wall reactors have a more uniform temperature distribution but the surface of the reactor walls can also get coated. This limits the reactor to one species. Used more for polycrystalline films. • In cold wall reactors, the reaction rate is reduced but film quality can be better controlled. Better for epitaxial films.
