Abstract:
1. A method of processing a substrate disposed in a process chamber, comprising: performing a process on a substrate disposed in a process chamber having a substrate support ring configured to support the substrate and a reflector plate disposed proximate a back side of the substrate; providing a first gas comprising one of an oxygen containing gas or a nitrogen containing gas to a back side of the substrate via one or more through holes disposed in the reflector plate while performing the process on the substrate; providing the first gas to a front side of the substrate at the same time as providing the first gas to the back side of the substrate; and maintaining the process chamber at a first pressure proximate a top surface of the substrate and at a second pressure proximate the bottom surface of the substrate, wherein the first pressure is greater than the second pressure sufficiently to prevent dislodgement of the substrate from the substrate support ring during processing.
