Abstract:
A substrate processing system configured to perform a deposition process on a substrate includes a substrate support including a plurality of zones and a plurality of resistive heaters arranged throughout the plurality of zones. The plurality of resistive heaters includes separately-controllable resistive heaters arranged in respective ones of the plurality of zones. A controller is configured to, during the deposition process, control the plurality of resistive heaters to selectively adjust temperatures within the plurality of zones.
