Patent ID: 8457479

Claim:
A method of manufacture of a semiconductor device for performing a rapid thermal processing of a semiconductor substrate, comprising: providing a rapid thermal processing apparatus which includes a processing chamber, a substrate support part arranged in the processing chamber and supporting the semiconductor substrate in contact with a rear surface of the semiconductor substrate, a lamp part optically irradiating a front surface of the semiconductor substrate and heating the semiconductor substrate, a thermo sensor provided to measure a temperature of the semiconductor substrate, a temperature computing part computing the temperature of the semiconductor substrate based on an output signal of the thermo sensor, and a control part controlling an irradiation intensity of the lamp part according to the temperature computed by the temperature computing part; performing, by the rapid thermal processing apparatus, the rapid thermal processing of the semiconductor substrate; and correcting a control parameter of the irradiation intensity of the lamp part based on a reflectivity of the front surface of the semiconductor substrate which is measured beforehand, wherein the correcting step comprises correcting the control parameter of the irradiation intensity of the lamp cart based on a correlation function indicating a relationship between the reflectivity of the front surface of the semiconductor substrate and a difference in a maximum temperature of the semiconductor substrate and the substrate support part.
