Abstract
A processing chamber and a processing method for processing a substrate in the processing chamber with thermal control are described herein. The method includes heating a first substrate using a heater apparatus during a first processing operation. The heater apparatus has a first setpoint during at least a first portion of the first processing operation. The first substrate is disposed on a substrate support surface of an electrostatic chuck in a processing chamber. The method further includes determining a first parameter change corresponding to a resistivity change in the electrostatic chuck, determining a second setpoint for the heater apparatus based on the first parameter change, and controlling the heater apparatus to the second setpoint.
