Claim:
1. A substrate processing method of processing a substrate, comprising: a) performing chemical-solution processing by supplying a chemical solution to an upper surface of a substrate held in a horizontal state in a state where a shielding plate that opposes said upper surface of said substrate is located at a first relative position relative to said substrate in an up-down direction; b) after said operation a), pushing a chemical atmosphere existing in a space between said shielding plate and said substrate out around said substrate by moving said shielding plate relative to said substrate in said up-down direction from said first relative position to a second relative position that is closer to said substrate than said first relative position; c) after said operation b), performing cleaning processing by supplying a cleaning liquid to said upper surface of said substrate in a state where said shielding plate is located at said second relative position; d) after said operation c), moving said shielding plate relative to said substrate in said up-down direction from said second relative position to a third relative position that is closer to said substrate than said second relative position; e) after said operation d), performing dry processing by rotating said substrate in a state where said shielding plate is located at said third relative position.
