Claim 0:
1. A method for creating correction data comprising:
selecting a setting voltage among a plurality of setting voltages determined in advance,
supplying the selected setting voltage to a heater for heating a substrate support on which a substrate is supported;
adjusting, at the setting voltage supplied to the heater, a power supplied to the heater such that a resistance of the heater becomes a resistance value corresponding to a predetermined first temperature based on temperature conversion data indicating a relationship between the resistance of the heater and a temperature of the heater;
measuring a temperature of the substrate support, at a position where the heater is disposed, as a second temperature;
calculating a correction value corresponding to a difference between the predetermined first temperature and the second temperature; and
creating correction data indicating a corresponding relationship between each of the setting voltages and the correction value,
wherein said selecting, said supplying, said adjusting, said measuring of the temperature, said calculating of the correction value, and said creating are executed for each of the setting voltages, and
the correction data is created for each of the setting voltages.
