Patent ID: 7893387

Claim:
A 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 support base positioned below 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; one or more temperature sensors coupled to said substrate support or said support base or both said substrate support and said support base, and configured to measure at least one temperature of said substrate support, said support base, or said substrate, or a combination of two or more thereof; 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 one or more temperature sensors, and configured to change the temperature of said substrate from a first processing temperature to a second processing temperature by: selecting a plurality of PID parameter sets, each PID parameter set in said plurality of PID parameter sets including a proportional constant K P1 , an integral constant K I1 , and a derivative constant K D1 , and changing the temperature of said substrate from said first processing temperature to said second processing temperature using a PID parameter set provided in said plurality of PID parameter sets for a ramp period of time and continuing to change the temperature of said substrate from said first processing temperature to said second processing temperature using each of the remaining PID parameter sets provided in said plurality of PID parameter sets in sequence for another ramp period of time, said another ramp period of time following said ramp period of time.
