Abstract:
A method for the removal of particles and liquid from at least one surface of a substrate using at least one rotating pad, the method comprising the steps of:creating a relative linear motion at a predetermined speed between the at least one wetted rotating pad and the substrate; contacting said surface of said substrate at a first edge with the at least one wetted rotating pad; applying a substance on said surface adjacent to the at least one wetted rotating pad and applying the substance between the at least one wetted rotating pad and said first edge, said substance reducing surface tension of said liquid, said substance being at least partially miscible with said liquid and when mixed with said liquid yielding a mixture having a surface tension being lower than that of said liquid; and continuing said linear relative motion from said first edge to a second edge, opposite to said first edge, while contacting said surface of said substrate with the at least one wetted rotating pad and while supplying said substance, the step of continuing said linear relative motion thereby removing at least a portion of said particles and at least a portion of said liquid from said surface of said substrate.
