摘要： Methods for polishing tungsten are provided. During ECMP, increasing the voltage to the pad is not always enough to increase the polishing rate. When polishing tungsten, simply increasing the applied voltage will, in some cases, actually decrease the removal rate. By increasing the down force pressure between the polishing pad and the substrate, the applied voltage, and the rotation speed of the substrate and the polishing pad, the tungsten removal rate will also increase.

摘要： Embodiments of a conditioning head for in-situ conditioning and/or cleaning a processing pad of a CMP, ECMP, or other processing system are provided. In one embodiment, the conditioning head includes a brush disposed in a central cavity. A cleaning fluid is provided through the central cavity of the conditioning head to a processing pad. The brush spins and moves laterally across the surface of the processing pad. The cleaning solution dispensed through the conditioning head dissolves by-products of the processing operation while the brush gently wipes the processing pad. A lip of the conditioning head retains the cleaning fluid and cleaning waste, thereby minimizing contamination of the area outside of the conditioning head. The cleaning waste is removed from the processing pad via passages formed near the outer periphery of the conditioning head.
