Claim 11:
12. A substrate processing method, comprising:
moving a nozzle, which is configured to supply a fluid onto a top surface of a substrate, in a diametrical direction of the substrate in a state that the substrate is held horizontally and is being rotated around a vertical rotation axis;
detecting a collision angle of the fluid on the top surface of the substrate; and
controlling a discharge amount of the nozzle to reduce a deviation between a detection value of the detecting and a set value,
wherein the nozzle comprises a first nozzle member configured to discharge the fluid and a second nozzle member configured to discharge the fluid in a direction different from a direction in which the first nozzle member discharges the fluid,
a first discharge line as an extension line of a flow path from the first nozzle member and a second discharge line as an extension line of a flow path from the second nozzle member intersect with each other at an intersection point, and
at least one of a discharge amount of the first nozzle member or a discharge amount of the second nozzle member is varied while the nozzle is being moved in the diametrical direction of the substrate.
