Abstract:
1. In combination, a substrate processing apparatus and a substrate, wherein a processing liquid is supplied to one major surface of a substrate for a predetermined substrate processing, comprising: three or more support members disposed in said processing apparatus, which abut a peripheral edge of said substrate and accordingly support said substrate; said substrate having a notch at said peripheral edge of said substrate; an atmosphere blocking member which faces another major surface of said substrate and is spaced away from said substrate; said atmosphere blocking member having a radius which is smaller than a radius of said substrate by a radial width of the notch at the peripheral edge of said substrate, and is so constructed and arranged that a peripheral edge of said atmosphere blocking member is not exposed around said substrate through the notch; wherein a substrate-facing surface of said atmosphere blocking member which faces the other major surface of said substrate becomes closer to the other major surface of said substrate with a distance toward said peripheral edge of said atmosphere blocking member; said three or more support members being disposed at a said peripheral edge of said atmosphere blocking member; and a gas supplying unit which supplies an atmosphere gas to a space which is created between said atmosphere blocking member and said substrate.
