Abstract
Embodiments of the present invention provide apparatus and method for reducing non uniformity during thermal processing. One embodiment provides an apparatus for processing a substrate comprising a chamber body defining a processing volume, a substrate support disposed in the processing volume, wherein the substrate support is configured to rotate the substrate, a sensor assembly configured to measure temperature of the substrate at a plurality of locations, and one or more pulse heating elements configured to provide pulsed energy towards the processing volume.
