Abstract:
A system for processing a conductive material on a surface of a wafer using a solution, the system comprising:an electrode; a mask having a first surface and a second surface, the mask comprising a plurality of openings extending between the first and second surfaces and being supported between the electrode and the surface of the wafer, wherein the mask and the surface of the wafer are configured to establish relative motion therebetween during the processing; and a conductive mesh positioned between the first surface of the mask and the electrode and attached to the mask such that the plurality of openings of the mask defines a plurality of active regions of the conductive mesh for controlling the uniformity of processing the conductive material on the surface of the wafer, wherein the conductive mesh is connected to a power input.
