Abstract:
A system for generating a first silicon nitride film on at least a portion of an inner surface of a chamber and a second silicon nitride film on a substrate, comprising:the chamber configured to house the substrate for processing; at least one pre-treatment source gas for generating the first silicon nitride film in the chamber; at least one source gas for generating a film on a substrate; a system controller configured to control the introduction from the at least one source gas into the chamber; and a memory coupled to the controller comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of the system, the computer-readable program comprising: instructions for controlling a gas delivery system prior to the introduction of the substrate, to introduce the at least one pre-treatment source gas into the chamber in an amount sufficient to form the first silicon nitride film of about 50 to 5000 Ã¥ per minute by thermal chemical vapor deposition to inhibit outgassing from chamber components; instructions for controlling a temperature from about 600Â° C. to about 800Â° C. and a pressure from about 100 Torr to about 500 Torr; and instructions for controlling the gas delivery system to introduce the at least one source gas into the chamber to form a film on the surface of a substrate introduced into the chamber by thermal chemical vapor deposition.
