Claim 0:
1. A substrate processing apparatus comprising:
a substrate holder configured to hold a substrate;
a rotary driver configured to rotate the substrate holder around a rotation axis;
a processing liquid nozzle configured to eject a processing liquid toward a peripheral portion of the substrate; and
a gas nozzle configured to eject a gas toward the processing liquid from a time at which the processing liquid is ejected from an ejection port of the processing liquid nozzle until 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.
