Abstract:
A susceptor is preheated through light irradiation by a halogen lamp before the first semiconductor wafer of a lot as a processing target is transferred into a chamber. The temperature of the susceptor is measured by a radiation thermometer. A control unit is configured to control the output of the halogen lamp so that the temperature of the susceptor reaches a stable temperature based on a result of the measurement of the temperature of the susceptor by the radiation thermometer. The stable temperature of the susceptor is the temperature of the susceptor when the temperature of the susceptor is risen to a constant temperature by continuously performing light irradiation heating on a plurality of semiconductor wafers in the chamber without heating the susceptor.

Claim (Index 1):
A thermal processing apparatus configured to heat a substrate by irradiating the substrate with light, the apparatus comprising:\n a chamber housing a substrate; a susceptor provided inside said chamber and configured to support when the substrate is placed on said susceptor; a light irradiation unit configured to irradiate the substrate placed on said susceptor with light; a temperature measurement unit configured to measure the temperature of said susceptor; and a control unit configured to control said light irradiation unit so that said susceptor is heated through light irradiation by said light irradiation unit based on a result of the measurement of the temperature of said susceptor by said temperature measurement unit before the first substrate of a lot is transferred into said chamber.
