Abstract: A plurality of substrate support pins are erected on a susceptor that holds a semiconductor wafer that is an object being treated. The plurality of substrate support pins are set in a ring shape at equal intervals. A flash lamp irradiates the semiconductor wafer supported by the plurality of substrate support pins with flash light to heat the semiconductor wafer. The radius of a setting circle in which the plurality of substrate support pins are set is made larger as the pulse width of flash light emitted from the flash lamp decreases. To irradiate the semiconductor wafer with flash light while having the semiconductor wafer supported by the plurality of substrate support pins can prevent cracking of the semiconductor wafer despite possible abrupt deformation of the semiconductor wafer due to the flash-light irradiation.
