Patent ID: 7670473

Claim:
A method of electrochemical mechanical processing a conductive surface of a workpiece using a solution, comprising: disposing the solution onto the conductive surface of the workpiece; electrochemically mechanically processing the conductive surface in the presence of the solution while relative movement and physical contact exists between a top surface of a workpiece surface influencing device and the conductive surface, wherein the top surface of the workpiece surface influencing device is a ceramic material that presents a substantially planar contact area to the conductive surface, the contact area including a plurality of contact regions formed over a conducting material having recessed and raised regions, and wherein a plurality of channels are formed through the top surface through which the solution passes, wherein each of the plurality of contact regions is formed over the conducting material as a separable sweeper; and inserting each separable sweeper into the workpiece surface influencing device prior to disposing the solution.
