Abstract:
1. A substrate processing method, comprising processing a substrate using an apparatus which includes: a chamber; a gas introducing portion; a gas discharge port; a substrate transfer gate; a substrate moving member which moves said substrate between a substrate processing position where said substrate is processed in said chamber and a substrate transferring in-out position in said chamber where said substrate transferred into said chamber from said substrate transfer gate is located and where said substrate is located when said substrate is transferred out from said chamber through said substrate transfer gate, said gas introducing portion, said substrate processing position, said gas discharge port and said substrate transfer gate being disposed in this order; a gas restraining member which restrains processing gas for processing said substrate from flowing toward said substrate transfer gate and which is provided between said gas discharge port and said substrate transfer gate; and a cover plate, said chamber including a step portion projecting from an inner wall of a sidewall of said chamber, and said step portion being located between said gas discharge port and said substrate transfer gate, wherein in a state in which said substrate is placed on said substrate moving member and is positioned at said substrate processing position, and said cover plate is placed on said substrate moving member extending toward the sidewall of said chamber from a periphery of said substrate and having a clearance between the sidewall of said chamber and said cover plate, said processing gas is introduced above and onto said substrate from said gas introducing portion, and a majority of said gas which has flowed above and on said substrate then flows into a discharge buffer space constituted below said cover plate by said cover plate, a sidewall of said substrate moving member, the sidewall of said chamber and said step portion through said clearance, and is discharged out from said gas discharge port to process said substrate.
