Patent ID: 8522799

Claim:
An apparatus for cleaning a substrate, comprising: a manifold unit located at a first vertical position, the manifold unit having a first row of channels defined within the manifold unit and configured to supply a foam to the surface of the substrate when present; and a proximity head unit positioned at a second vertical position, the second vertical position being proximate to a surface of the substrate and closer to the surface of the substrate than the first vertical position of the manifold unit when the substrate is present, such that the proximity head unit is below the manifold unit, the proximity head unit having a second row of channels defined within the proximity head unit and configured to supply a fluid to the surface of the substrate when present; and a third row of channels defined within the proximity head unit and positioned horizontally between the first and second row of channels such that the first row of channels and the second row of channels are on horizontal opposite sides of the third row of channels, the second row of channels are coupled to a vacuum and oriented over the surface of the substrate when the substrate is present, thereby controlling removal of the foam and the fluid; wherein the surface is of one side of the substrate.
