Claim:
1. A substrate processing method of processing a substrate, comprising the steps of: a) holding a substrate with a main surface thereof directed upward in an internal space of a chamber and forming a pattern on said main surface of said substrate; b) bringing said internal space of said chamber into a reduced pressure atmosphere and supplying a processing liquid onto a center portion of said main surface of said substrate while rotating said substrate in said reduced pressure atmosphere, to thereby coat said main surface of said substrate with said processing liquid; and c) increasing pressure in said internal space of said chamber and continuously supplying said processing liquid onto said main surface of said substrate coated with said processing liquid while rotating said substrate, to thereby perform a predetermined processing after said step b), wherein the number of revolutions of said substrate in said step c) is smaller than that of said substrate in said step b).
