Patent ID: 6858923

Claim:
A substrate processing system comprising: a housing defining a process chamber; a substrate holder adapted to hold a substrate during substrate processing; a heater operatively coupled to heat said substrate holder; a gas delivery system configured to introduce gases into said process chamber; a controller for controlling said gas delivery system and said heater, and a memory coupled to said controller comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of said controller, said computer-readable program including instructions to control said gas delivery system to flow a process gas into the substrate processing chamber and to control said heater to heat the substrate holder to form a carbon doped silicon oxide insulation layer over the substrate with said process gas; instructions to thereafter control said gas delivery system to introduce a reducing gas into the chamber to densify the insulation layer; and instructions to thereafter control the substrate processing system to cure the carbon doped silicon oxide layer.
