Abstract

In a substrate processing method according to the present invention, a substrate is first processed using a chemical liquid. Next, the substrate is rinsed by supplying a rinsing liquid thereto while the substrate is being rotated. Thereafter, the substrate is dried while the substrate is being rotated. The drying of the substrate includes reducing a rotating speed of the substrate to a first rotating speed lower than that of the substrate during 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 drying liquid to the substrate, after the rinsing liquid supply position has been moved.
