Classification: CPC H  B | IPC B  H

Claim 15:
16. A substrate processing method comprising:
rotating a substrate around a rotation axis;
ejecting a processing liquid from a processing liquid nozzle to a peripheral portion of the rotating substrate; and
ejecting a gas from a gas nozzle toward the processing liquid from a time at which the processing liquid is ejected from an ejection port of the processing liquid nozzle to a time at which the processing liquid arrives at a liquid arrival point on the substrate,
wherein a flight trajectory of the processing liquid is changed by the gas ejected through the gas nozzle, and
wherein droplets separated from the substrate are blown off to an outside of the substrate in a radial direction by the gas ejected from the gas nozzle.
