Abstract:
An apparatus for washing and drying substrates one by one, comprising:a spin chuck for holding a substrate such that a surface thereof to be processed faces upward and for rotating the substrate;a process fluid supply mechanism for selectively supplying one or two or more of a plurality of kinds of process fluids to the surface to be processed of the substrate rotated by the spin chuck;a dry gas supply mechanism for selectively applying one or more of a plurality of kinds of dry gases to the surface to be processed of the substrate rotated by the spin chuck;a nozzle assembly having a first discharge port and a second discharge port communicating with the process fluid and dry gas supply mechanism respectively, the first discharge port discharging a first process fluid which is in a liquid phase under conditions of room temperature and atmospheric pressure, and the second discharge port discharging a second process fluid which is in a gas phase under conditions of room temperature and atmospheric pressure, the first discharge port and the second discharge port being adjacent to each other in the nozzle assembly;a driving mechanism for moving the nozzle assembly to a location above the substrate held by the spin chuck; anda controller for controlling operations of the process fluid and dry gas supply mechanisms and the driving mechanism.
