Abstract

A heat treating apparatus for heat treating a substrate by irradiating the substrate with light includes a heat treating chamber for receiving the substrate, a heating plate for preheating the substrate through a thermal diffuser plate, xenon flashlamps for heating the substrate preheated by the heating plate, to a treating temperature by irradiating the substrate with flashes of light, and a decompression mechanism for decompressing the heat treating chamber when the xenon flashlamps heat the substrate.
