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.
