    摘要: Workpieces, such as semiconductor wafers, are electroplated with improved thickness uniformity by providing a diffuser member intermediate the cathode and anode of a fountain-type electroplating apparatus. The diffuser or member has a pattern of openings specifically designed to prevent channeling and/or selective directing of electrolyte towards the workpiece. In one embodiment, the diffuser member comprises a spiral-shaped pattern of openings originating at the center of the diffuser member and extending to the periphery thereof.

    摘要: A semiconductor device is provided with a tantalum layer to line the channels and vias of a semiconductor, a tungsten nitride layer at a low temperature on the tantalum layer, and a copper conductor layer on the tungsten nitride layer. The tungsten nitride acts as a highly efficient copper barrier material with high resistivity while the tantalum layer acts as a conductive barrier material to reduce the overall resistance of the barrier layer.

    摘要: A method is provided for forming seed layers in semiconductor device channels or vias by using an inert gas sputter etching technique. The technique etches back the seed layers which results in a reduction of seed layer overhang at the top of the channels or vias, thereby enhancing the subsequent filling of the channel or vias by conductive materials.
