    摘要: An electrochemical apparatus is provided which deposits material onto or removes material from the surface of a workpiece. The apparatus comprises a polishing pad and a platen which is in turn comprised of a first conductive layer in contact with the polishing pad and coupled to a first potential, a second conductive layer coupled to a second potential, and a first insulating layer disposed between the first and second conductive layers. At least one electrical contact is positioned within the polishing pad and is electrically coupled to the second conductive layer. A reservoir is provided which places an electrolyte solution in contact with the polishing pad and the workpiece. A carrier positions and/or presses the workpiece against the polishing pad.

    摘要: A slurry for use in a chemical mechanical planarization process for a wafer comprises a chemical portion and a mechanical portion. The chemical portion comprises a surfactant that forms a layer over a metallic layer of the wafer to decreasing dishing to less than an average of 843 Å reduce the static etch rate of the metallic layer. The mechanical portion comprises an abrasive agent to assist in the planarization of the metallic layer of the wafer. In another embodiment, a slurry for polishing a copper layer formed over a first layer is disclosed. The slurry comprises an abrasive agent; and a surfactant comprising at least one non-ionic surfactant to reduce the static etch rate of the copper layer. The shelf life of the slurry exceeds 90 days.

    摘要: A method and associated composition for chemical mechanical planarization of a chalcogenide-containing substrate (e.g., germanium/antimony/tellurium (GST)-containing substrate) are described. The composition and method afford low defect levels as well as low dishing and local erosion levels on the chalcogenide-containing substrate during CMP processing.
