Abstract:
1. A method of processing that includes conditioning a workpiece surface influencing device, the workpiece surface influencing device being used during at least a portion of at least one electrochemical mechanical process that operates upon a workpiece using a solution, the method comprising: operating upon the workpiece using the solution in the electrochemical mechanical process, with the workpiece surface influencing device being disposed in proximity to the workpiece for a period of time during the electrochemical mechanical process, the electrochemical mechanical process also resulting in accumulation of conductive particles onto the workpiece surface influencing device; and conditioning the workpiece surface influencing device before performing another electrochemical mechanical process, the step of conditioning including applying a potential difference between an electrode and a conditioning member, the application of the potential difference during the step of the conditioning resulting in one of the number of accumulated conductive particles being reduced and the size of the accumulated conductive particles being reduced.
