Abstract:
1. An apparatus for processing a substrate, comprising: a chamber body having a processing volume; a substrate support that is disposed in the processing volume; a plurality of heat lamps positioned below the substrate support and configured to transfer an amount energy to a region of a surface of a substrate that is disposed on the substrate support; a lamp module controller configured to adjust and control a power level of one or more of the lamps; a temperature sensor assembly that is configured to measure a temperature profile of the region of the surface of the substrate, wherein the temperature sensor assembly comprises an infrared camera that is positioned above the substrate support; a substrate support controller having a position sensor assembly, wherein the substrate support controller is coupled to the substrate support and is configured to monitor and to control an angular position and a rotation speed of the substrate support; and a system controller that is in communication with the lamp module controller, the substrate support controller and the temperature sensor assembly wherein the system controller is configured to receive data from at least the substrate support controller and the temperature sensor assembly, to calculate appropriate power levels for the lamps and an appropriate rotation speed of the substrate support, to provide instructions to the lamp module controller to adjust the power levels of the lamps, and to provide instructions to the substrate support controller to adjust the angular position and the rotation speed of the substrate support.
