Classification: CPC H | IPC H

Claim 17:
18. 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 second nozzle member includes second nozzle members, and four or more second nozzle members are equi-spaced around the first discharge line,
wherein the nozzle further comprises a revolving unit configured to revolve the second nozzle member around the first discharge line.
