Claim Text:
1. A substrate processing method comprising: a chemical liquid process that supplies a chemical liquid to a substrate; a rinse process that supplies a rinse liquid to the substrate after the chemical liquid process; and a drying process that dries the substrate after the rinse process, wherein the drying process comprises: a first drying process that rotates the substrate at a first rotational speed; a second drying process that decreases a rotational speed of the substrate to a second rotational speed lower than the first rotational speed after the first drying process; and a third drying process that increases the rotational speed of the substrate from the second rotational speed to a third rotational speed after the second drying process, and a drying solution is supplied to the substrate from a starting time point of the first drying process to a time point falling within the third drying process.
