    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 for the cleaning of wafers typically during a chemical mechanical polishing (CMP) process. The method includes polishing a material layer on a wafer in sequential polishing steps, rinsing the wafer using a novel surfactant composition solution after at least one of the polishing steps and rinsing of the wafer using deionized water, respectively. The surfactant composition solution imparts a generally hydrophilic character to a hydrophobic material layer such as a high-k dielectric layer on the wafer. Consequently, the layer is rendered amenable to cleaning by deionized water, thereby significantly enhancing the removal of particles from the layer and reducing the number of defects related to the CMP process.

    摘要: A semiconductor device 100 includes a low-k dielectric insulator 104. In the preferred embodiment, a low-k dielectric material 104 is deposited. This material 104 is then cured using a plasma cure step. The cure process causes the density of the top portion 106 of layer 104 to be increased. The higher density portion 106, however, also has a higher dielectric constant. As a result, the dielectric constant of the layer 104 can be reduced by removing this higher density portion 106. This leads to a lower dielectric constant (e.g., less than about 3) of the bulk film.
