Patent ID: 7441299

Claim:
An apparatus for use in processing a substrate, comprising: a brush enclosure extending over a length, the brush enclosure configured to be disposed vertically over a horizontal surface of the substrate, the brush enclosure having an open region that is configured to be disposed in proximity to the horizontal surface of the substrate, the open region enabling foam from within the brush enclosure to contact the surface of the substrate when the substrate is present, the open region extending over the length of the brush enclosure; a first flange extending outward from the brush enclosure along the length and along a first side of the open region; a second flange extending from the brush enclosure along the length and along a second side of the open region, wherein a flat bottom surface of the first and second flange is substantially parallel to the horizontal surface of the substrate, wherein the first and the second flanges each have an opening extending therethrough, the opening connected to a vacuum source for removing fluid through the opening, the fluid present between the flat bottom surface and the horizontal surface of the substrate; and a brush disposed within the brush enclosure, the brush configured to deliver a fluid to the horizontal surface of the substrate through a conduit defined around an axis of the brush.
