Claim 10:
11. A substrate processing apparatus, comprising:
a holder configured to hold a substrate horizontally;
a substrate rotating unit configured to rotate the holder and the substrate thereon around a vertical rotation axis;
a nozzle configured to supply a fluid onto a top surface of the substrate held by the holder;
a supply unit configured to supply the fluid to the nozzle; and
a moving unit configured to move the nozzle in a diametrical direction of the substrate,
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,
the supply unit comprises a first flow rate controller configured to control a discharge amount of the first nozzle member and a second flow rate controller configured to control a discharge amount of the second nozzle member independently from the discharge amount of the first nozzle member,
wherein the nozzle further comprises a revolving unit configured to revolve the second nozzle member around the first discharge line.
