Abstract:
A substrate processing apparatus comprising:a processing chamber having a chamber body;a gas delivery system configured to deliver a gas to said processing chamber;a heater pedestal having a surface for supporting a substrate within said chamber;a heat exchange system including a passage in said chamber body through which a heat exchange medium may be circulated;a controller configured to control said gas delivery system, said heat exchange system, and said heater pedestal; anda memory, coupled to said controller, comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of said substrate processing apparatus, said computer-readable program including:(a) computer instructions for controlling said heat exchange system to circulate said heat exchange medium through said passage to maintain a heat exchange temperature of about 60.degree. C. or less;(b) computer instructions for heating said heater pedestal to a heater temperature; and(c) computer instructions for controlling said gas delivery system to flow said gas at a flow rate to deposit a film on said substrate, said flow rate providing an effective temperature of said substrate lower than said heater temperature, wherein said film meets uniformity and resistance specifications after deposition onto a number of substrates, said number being less than twenty-five.
