Abstract:
1. A method of preparing a wafer surface, comprising the operations of: providing a brush mounted in a housing, the brush having a surface for scrubbing the wafer surface; partially surrounding the surface of the brush with a plurality of meniscus-forming ports in the housing; applying the plurality of meniscus-forming ports proximate to the wafer surface; scrubbing the wafer surface using the surface of the brush and simultaneously activating the plurality of meniscus-forming ports to form a meniscus on the wafer surface, wherein the meniscus contains fluids at least partially around the brush; and scanning the housing relative to the wafer surface so that the brush and the ports move across the wafer surface and the meniscus dries the wafer surface after the brush scrubs the wafer surface.
