Abstract: PURPOSE:To provide the semiconductors with excellent properties by heat treatment at a high temperature for a short time by a method wherein a heat treatment vessels containing silicon wafers are fed with oxidative gas and the wafers are irradiated with lamp light. CONSTITUTION:A cover 5a of the first quartz chamber 2a is opened to mount the first silicon wafer 3a on a wafer holding base 4a and then the first quartz chamber 2a is fed with a lot of processing gas for purging to fill the chamber 2a with said gas within a short time. Successively the gas flow rate is throttled by a flow rate adjusting valve 10a to restrain the wafer 3a from cooling down during heat treatment simultaneously halogen lamps 1a are lighted to perform the heat treatment by photo irradiation. The silicon wafers 3a, 3b may be heat- treated continuously by repeating operation alternately in the first and the second chambers 2a, 2b. Through these procedures, the heat conductive speed may be accelerated since the light may be absorbed both from surface and backside.
