Abstract:
1. A thermal processing apparatus for performing a processing accompanied with heating on a substrate, comprising: a chamber body forming a space in which a substrate is processed; a substrate supporting part for supporting a lower surface of a substrate by a bottom surface of a recessed portion whose depth is larger than a thickness of said substrate and surrounding a periphery of said substrate by a side wall portion of said recessed portion inside said chamber body; a heating part for heating said substrate supporting part; a substantially plate-like cover member disposed above said substrate supporting part: a closing mechanism for closing said recessed portion by bringing said cover member into contact with an upper end of said side wall portion, said cover member being relatively movable onto said side wall portion while said substrate is preheated by said substrate supporting part; and a flash lamp disposed and operable for heating said substrate by emitting a flash light to said substrate through said cover member, said recessed portion being closed by said cover member.
