Abstract
Immediately after a cold substrate G is placed on a substrate table, a large electric power Pis supplied to a heating elementembedded in the substrate table for a time period Tso that temperature of the substrate table overshoots a target temperature, and thereafter zero or very small electric power Pis supplied to the heating element for a time period Tso that the temperature of the substrate tableis lowered to the target temperature while temperature of the substrate continues to rise up to the target temperature. When both the temperature of the substrate table and of the substrate reaches approximately to the target temperature after the time period Thas elapsed, control of the electric power is entrusted to a PID controller.
