Abstract:
A method of operating a substrate processing chamber, said method comprising:cleaning material deposited on at least one interior surface of said chamber by reacting said material with a fluorine-containing gas, said cleaning step leaving a residue comprising fluorine atoms on at least a portion of said at least one interior surface;thereafter, depositing a silicon oxide film over said at least one interior surface of said chamber by introducing a process gas comprising silicon and oxygen into said chamber, said silicon oxide film substantially covering said portion of said at least one interior surface;wherein conditions of said depositing step are selected so that said deposited silicon oxide film exhibits substantially no fluorine out gassing during thermal desorbtion spectra testing when heated up to 600.degree. C. after being deposited over a test substrate placed in the chamber during said depositing step.
