Abstract:
An apparatus for processing substrates, comprising:a nozzle plate; and aligned with an upper surface of said nozzle plate, wherein said at least one first nozzle plate is capable of providing outwardly directed uniform flow over the upper surface of said nozzle plate; a plurality of second nozzles disposed in said nozzle plate at an angle of less than 90Â° relative thereto, wherein said second nozzles and said at least one first nozzle are separately controllable, wherein said second nozzles provide a flow therefrom directed transverse to said radial flow from said at least one first nozzle, and wherein said second nozzles are distributed over the surface of said nozzle plate such that said transverse flow therefrom deflects said radial flow from said at least one first nozzle into a spirally outwardly extending flow.
