    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.

    摘要： Polishing compositions and methods for removing conductive materials from a substrate surface are provided. In one aspect, a method is provided for processing a substrate to remove conductive material disposed over narrow feature definitions formed in a substrate at a higher removal rate than conductive material disposed over wide feature definitions formed in a substrate by an electrochemical mechanical polishing technique. The electrochemical mechanical polishing technique may include a polishing composition comprising an acid based electrolyte system, one or more chelating agents, one or more corrosion inhibitors, one or more inorganic or organic acid salts, one or more pH adjusting agents to provide a pH between about 2 and about 10, and a solvent.

    摘要： Polishing compositions and methods for removing conductive materials from a substrate surface are provided. In one aspect, a composition includes an acid based electrolyte system, one or more chelating agents, one or more corrosion inhibitors, one or more inorganic or organic acid salts, one or more pH adjusting agents to provide a pH between about 2 and about 10, a polishing enhancing material selected from the group of abrasive particles, one or more oxidizers, and combinations thereof, and a solvent. The composition may be used in an conductive material removal process including disposing a substrate having a conductive material layer formed thereon in a process apparatus comprising an electrode, providing the composition between the electrode and substrate, applying a bias between the electrode and the substrate, and removing conductive material from the conductive material layer.
