Abstract
A method for cleaning silicon carbide and/or organosilicate layers from interior surfaces of a process chamber is disclosed. In one aspect, silicon carbide and/or organosilicate layers are cleaned from interior surfaces of a process chamber by treating it with a hydrogen/fluorine-based plasma. In another aspect, silicon carbide and/or organosilicate layer are cleaned from interior surfaces of the process chamber by treating it with a hydrogen-based plasma followed by a fluorine-based plasma. Alternatively, silicon carbide and/or organosilicate layers are cleaned from interior surfaces of the chamber by treating it with a fluorine-based plasma followed by a hydrogen-based plasma.
