    摘要: By using signals from an electric drive assembly of an electroplating tool, the operating position of the substrate surface to be plated may be determined in an automated fashion wherein, based on a reference position, the meniscus of the electrolyte and/or any appropriate operating position may be determined. Consequently, accuracy and throughput may be enhanced compared to conventional manual or semi-automatic adjustment procedures.

    摘要: A plating tool for a single-use plating process comprises a reclaim system in combination with a support tank to enable collection of non-consumed plating solution drained off from the process chamber, which is then re-circulated to the support tank after an efficient treatment in the reclaim system. Since the non-consumed plating solution is continuously recycled, the electrolyte may be preserved substantially without any time limit while at the same time production costs for a single-use plating process are significantly reduced.

    摘要: The present invention is directed to methods and apparatuses for removing bubbles from a process liquid. The process liquid can comprise a plating solution used in a plating tool. The process liquid is supplied to a tank. A plurality of streams of the process liquid are directed towards a surface of the process liquid from below. This can be done by feeding the process liquid to a flow distributor comprising a plurality of openings providing flow communication between an inner volume of the flow distributor and a main volume of the tank. Before leaving the tank through an outlet, the process liquid flows through a flow barrier.

    摘要: A conductive cap material for a copper region may be provided with enhanced etch resistivity by taking into consideration the standard electrode potential of one or more of the species contained therein. For example, instead of a conventionally used CoWP alloy, a modified alloy may be used, by substituting the cobalt species by a metallic species having a less negative standard electrode potential, such as nickel. Consequently, device performance may be enhanced, while at the same time the overall process complexity may be reduced.
