    Abstract: A method for thermally processing a semiconductor substrate comprises: heating the substrate to a target peak temperature while controlling the gas pressure in the processing chamber at a pressure level that is significantly lower than atmospheric pressure; providing a flow of a purge gas between the substrate and a thermal reservoir at or near the time the substrate temperature reaches the target peak temperature while adjusting the gas pressure in the processing chamber to a second pressure level. Preferably, the purge gas has a relatively high thermal conductivity.

    Abstract: In a system for thermal processing of a semiconductor substrate, a reflector plate has a stepped surface facing the substrate during heating and cooling of the substrate. The raised surface of the reflector plate has reduced reflectivity, providing advantages during, among other things, cooling of the substrate. The reflector plate also includes a number of recesses to which one or more pyrometers are coupled. These recesses have a highly reflective surface, providing advantages in the performance of the pyrometers.
