    摘要: A method and apparatus are provided for polishing a substrate surface. In one aspect, an apparatus for polishing a substrate includes a basin and a polishing head. A carrier is disposed in the basin and has a substrate supporting surface. A retaining ring is disposed on the carrier and at least partially circumscribes the substrate supporting surface. The polishing head is supported above the basin and includes a conductive polishing pad. Embodiments may further include a vent to allow gas to escape through the polishing head. Embodiments may further include an electrolyte supply that flows electrolyte into the polishing head and out through a permeable electrode and the conductive pad to the substrate. Embodiments may also be configured with a polishing head diameter smaller than the substrate supported by the carrier.

    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.
