Classification: CPC H  F | IPC F  H

Claim 10:
11. A substrate processing system comprising:
a substrate support on which a substrate is supported;
a heater disposed in the substrate support to heat the substrate with a power supplied thereto;
a power supply unit configured to supply the power to the heater;
a measuring unit configured to measure a resistance of the heater;
a holding unit configured to hold temperature conversion data indicating a relationship between the resistance of the heater and a temperature of the heater and the correction data created by the method described in claim 1; and
a control unit,
wherein the control unit executes
measuring the setting voltage supplied to the heater;
measuring the resistance of the heater;
estimating the temperature of the heater based on the temperature conversion data,
specifying the correction value corresponding to the measured setting voltage from the correction data and correcting the estimated temperature of the heater using the specified correction value; and
controlling the power supplied to the heater based on the corrected temperature of the heater such that the temperature of the heater becomes a predetermined temperature.
