    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： Aspects of the invention generally provide a method and apparatus for polishing a substrate using electrochemical deposition techniques. In one aspect, an apparatus for polishing a substrate comprises a counter-electrode and a pad positioned between a substrate and the counter-electrode and a pad positioned between a substrate and the counter-electrode. A dielectric insert is positioned between the counter-electrode and the substrate. The dielectric insert has a plurality of zones, each zone permitting a separate current density between the counter-electrode and the substrate. In another embodiment, an apparatus for polishing a substrate that include a conductive layer comprises a counter-electrode to the material layer. The counter-electrode comprises a plurality of electrically isolated conductive elements. An electrical connector is separately coupled to each of the conductive elements.
