  • Patent number: 7947158
    Abstract: 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.
    Type: Grant

  • Publication number: 20050067288
    Abstract: In a storage tank for a process liquid, such as a plating liquid for a plating reactor, one or more barriers are implemented so as to define an inlet area and an outlet area, wherein a fluid flow path is substantially determined by the barrier to significantly suppress the migration of bubbles from the inlet area to the outlet area. In particular embodiments, the introduction of liquid into the storage tank is achieved by inlet lines terminating closely beneath the liquid surface so as to substantially avoid bubble generation and to remove moderately sized bubbles that are conveyed in the inlet lines.
