    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: An effective method for forming through-base wafer vias in the fabrication of stacked devices is described. The base wafer can be a silicon wafer in which case the method relates to TSV (through-silicon via) technology. The method affords high removal rates of both silicon and metal (e.g., copper) under appropriate conditions and is tuneable with respect to base wafer material to metal selectivity.
