Patent ID: 8906165

Claim:
A substrate processing method comprising: processing the substrate using a chemical liquid; rinsing the substrate by supplying a rinsing liquid thereto while the substrate is being rotated, after the chemical liquid process; and drying the substrate while the substrate is being rotated, after the rinsing of the substrate, wherein: the drying of the substrate includes: reducing a rotating speed of the substrate to a first rotating speed lower than that of the substrate in the rinsing of the substrate, while supplying the rinsing liquid to a central portion of the substrate; moving, from the central portion of the substrate toward a peripheral edge portion thereof, a rinsing liquid supply position to which the rinsing liquid is supplied, after the rotating speed of the substrate has been reduced to the first rotating speed; and supplying a diving liquid to the substrate, after the rinsing liquid supply position has been moved, wherein during the moving of the rinsing liquid supply position, a thin liquid film of the rinsing liquid, which is thinner than that in the rinsing of the substrate, is formed on the surface of the substrate, and wherein during the supplying of the drying liquid to the substrate, the liquid film of the rinsing liquid is replaced by the drying liquid.
