Abstract

A chemical liquid process is performed on a substrate. Then, a rinse process that supplies a rinse liquid to the substrate is performed. Thereafter, a drying process that dries the substrate is performed while rotating the substrate. The drying process includes a first drying process that rotates the substrate at a first rotational speed; a second drying process that decreases the rotational speed of the substrate to a second rotational speed lower than the first rotational speed after the first drying process. In the second drying process, the rinse liquid and a drying solution are agitated and substituted while generating braking effect. In a third drying process, the rotational speed of the substrate is increased from the second rotational speed to a third rotational speed after the second drying process. Thereafter, in a fourth drying process, the drying solution on the substrate is scattered away by rotating the substrate.
