Abstract
A brush cleaning apparatus includes a wafer support configured to support a wafer, and at least one cleaning brush moveable relative to the wafer support. The at least one cleaning brush has opposite first and second sides, and, on the first side, a planar cleaning surface configured to come into contact with the wafer supported by the wafer support to remove contaminants from the wafer.
