    摘要: An apparatus and method suitable for the pre-conditioning of a polishing pad on a CMP apparatus prior to the polishing of production wafers on the apparatus. The apparatus includes a pre-conditioning arm on which is mounted an ingot of suitable material. In use, the ingot is pressed against the polishing surface of the rotating polishing pad for a selected period of time to increase the temperature of the polishing surface by friction. The pre-conditioned polishing pad facilitates uniform polishing rates of production semiconductor wafers subsequently polished on the apparatus.

    摘要: A method for thinning a wafer is provided. In one embodiment, a wafer is provided having a plurality of semiconductor chips, the wafer having a first side and a second side opposite the first side, wherein each of the chips includes a set of through silicon vias (TSVs), each of the TSVs substantially sealed by a liner layer and a barrier layer. A wafer carrier is provided for attaching to the second side of the wafer. The first side of the wafer is thinned and thereafer recessed to partially expose portions of the liner layers, barrier layers and the TSVs protruding from the wafer. An isolation layer is deposited over the first side of the wafer and the top portions of the liner layers, barrier layers and the TSVs. Thereafter, an insulation layer is deposited over the isolation layer. The insulation layer is then planarized to expose top portions of the TSVs. A dielectric layer is deposited over the planarized first side of the wafer. One or more electrical contacts are formed in the dielectric layer for electrical connection to the exposed one or more TSVs.

    摘要: A method of protecting a low k dielectric layer that is preferably comprised of a material containing Si, O, C, and H is described. The dielectric layer is subjected to a gas plasma that is generated from a CXHY gas which is preferably ethylene. Optionally, hydrogen may be added to the CXHY gas. Another alternative is a two step plasma process involving a first plasma treatment of CXHY or CXHY combined with H2 and a second plasma treatment with H2. The modified dielectric layer provides improved adhesion to anti-reflective layers and to a barrier metal layer in a damascene process. The modified dielectric layer also has a low CMP rate that prevents scratch defects and an oxide recess from occurring next to the metal layer on the surface of the damascene stack. The plasma treatments are preferably done in the same chamber in which the dielectric layer is deposited.
