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. The ECMP polishing compositions and methods described herein improve the effective removal rate of materials from the substrate surface, such as copper, with a reduction in planarization type defects and yielding a desirable surface finish.

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: An apparatus and method for planarizing a surface of a substrate using a chamber separated into two parts by a membrane, and two separate electrolytes is provided. The embodiments of the present invention generally provide an electrochemical mechanical polishing system that reduces the number of defects found on the substrate surface after polishing. An exemplary electrochemical apparatus includes a physical barrier that prevents any trapped gas or gas generated during processing from residing in areas that can cause defects on the substrate. The process can be aided by the addition of various chemical components to the electrolyte that tend to reduce the gas generation at the cathode surface during the ECMP anodic dissolution process.
