Abstract:
1. A thermally zoned substrate holder for a processing system, comprising: a substrate support configured to support a substrate; one or more heating elements coupled to said substrate support, and configured to elevate a temperature of said substrate support; a plurality of temperature sensors coupled to said substrate support, and configured to respectively measure at least one temperature at a substantially central region of said substrate support or a substrate supported thereon or both, and at a substantially edge region of said substrate support or a substrate supported thereon or both; a support base coupled to said substrate support, and configured to support said substrate support; one or more cooling elements coupled to said support base, and configured to reduce or elevate a temperature of said support base; a thermal insulator disposed between said support base and said substrate support; and a temperature control system coupled to said one or more heating elements, said one or more cooling elements, and said plurality of temperature sensors, the temperature control system being configured to change the temperature of a substrate supported on said substrate support from a first temperature profile to a second temperature profile, after a period of time for processing the substrate at the first temperature profile, by:
