Abstract:
A spin, rinse, and dry station for spin rinsing a semiconductor wafer, comprising:a bowl having a bottom wall and a sidewall; a rotational member disposed in said bowl, said rotational member being attached to a rotatable shaft; a plurality of support members attached to said rotational member, said support members being configured to support a semiconductor wafer above said rotational member; a motor for rotating said rotatable shaft; and an adjustable nozzle assembly mounted in said bowl, said adjustable nozzle assembly being positioned so as to direct a spray of liquid toward a center of a bottom side of a semiconductor wafer supported in said bowl, wherein the adjustable nozzle assembly is disposed in an opening in the bottom wall of the bowl and includes a connector tube having a first end and a second end, an outer surface of said connector tube being threaded; a first cap having an opening therethrough, said first cap having a top surface and a threaded inner surface, and said first cap being threaded onto said first end of said connector tube; a second cap having an opening therethrough, said second cap having a top surface and a threaded inner surface, said second connector cap being threaded onto said second end of said connector tube; and a nozzle having a tubular portion defining a channel, said tubular portion being disposed in said opening of said first connector can so that a position of said nozzle can be vertically and rotationally adjusted.
