Abstract:
1. A heat treatment apparatus for performing a baking process on a thin film formed on a surface of a substrate, comprising: a chamber for receiving a substrate therein, the substrate having a surface with a thin film formed thereon; a holding part for holding said substrate within said chamber; a gas supply part for supplying a processing gas into said chamber; an exhaust part for exhausting an atmosphere from said chamber; a halogen lamp for irradiating said substrate held by said holding part with light to control said substrate at a predetermined temperature; a flash lamp for irradiating said substrate held by said holding part with flashes of light of which the irradiation time is 0.1 to 100 milliseconds; and a lamp control part configured to control said halogen lamp and said flash lamp so that the irradiation with light by said halogen lamp and the irradiation with flashes of light by said flash lamp start simultaneously from the beginning of said baking process and so that the irradiation with light from said halogen lamp continues beyond the irradiation with flashes of light.
