20120288261 | HEAT TREATMENT METHOD AND HEAT TREATMENT APPARATUS FOR HEATING SUBSTRATE BY IRRADIATING SUBSTRATE WITH LIGHT - A photodetector element for receiving radiated light from a surface of a semiconductor wafer loses a detection function because the intensity of the received light exceeds a detection limit while a flash lamp emits light.
