  • Patent number: 9988735
    Abstract: An electrochemical deposition system is described. The electrochemical deposition system includes one or more electrochemical deposition modules arranged on a common platform for depositing one or more metals on a substrate, and a chemical management system coupled to the one or more electrochemical deposition modules. The chemical management system is configured to supply at least one of the one or more electrochemical deposition modules with one or more metal constituents for depositing the one or more metals. The chemical management system can include at least one metal enrichment cell and at least one metal-concentrate generator cell.

  • Patent number: 9303329
    Abstract: Techniques disclosed herein include an electro-chemical deposition apparatus that provides an efficient circulation system, chemical management that provides reliable and uniform plating, and a configuration that provides short maintenance times and greater tool availability. Techniques include a processing tank containing an anolyte fluid, and one or more plating cells each having a catholyte fluid compartment with a circulation path that connects to a separate or remote catholyte reservoir. Thus, with such a configuration, a single pump can be used to flow catholyte (via manifolds) through one or more plating cells. Thus, with the catholyte reservoir maintained off board, instead of dumping catholyte over a weir into a reservoir, catholyte fluid—after flowing through a plating cell—is returned to the catholyte reservoir.

  • Patent number: 9017528
    Abstract: A process electrolyte replenishment module adapted to replenish ions in a process electrolyte in a substrate electrochemical deposition apparatus having a first anode and a first cathode, the replenishment module having a second anode. A process electrolyte recirculation compartment is disposed in the frame configured so that the process electrolyte is recirculating between the replenishment module and the deposition apparatus. An anode compartment is coupled to the process electrolyte recirculation compartment having the second anode, that is a soluble anode, for immersion in a secondary anolyte, and having a first ion exchange membrane being a cationic member separating the secondary anolyte from the process electrolyte.

  • Patent number: 9005409
    Abstract: An electrochemical deposition apparatus adapted to deposit metal onto a surface of a substrate, the apparatus has a frame configured for holding a process electrolyte. A substrate holder is removably coupled to the frame, the substrate holder supporting the substrate in the process electrolyte. An anode fluid compartment is removably coupled to the frame and containing an anolyte and having an anode facing the surface of the substrate, the anode fluid compartment further having a ion exchange membrane disposed between the anode and the surface of the substrate, the anode fluid compartment removable from the frame as a unit with the ion exchange membrane and the anode. The holder, the anode and the membrane are arranged in the frame so that ions from the anode pass through the ion exchange membrane into and primarily replenish ions in the process electrolyte depleted by ion deposition onto the surface of the substrate.

  • Publication number: 20150090599
    Abstract: This application relates to systems and methods for controlling current density in an electrochemical bath using an anode assembly that comprises a plurality of anodes arranged across a surface of the anode assembly. In one embodiment, each of the anodes may be coupled to a power supply through an intervening electrical switch. A switch controller enables the selection of which anodes should be turned on or off during processing. In this way, current density across the anode assembly can be controlled in a uniform manner by turning on and off select anodes. Turning off a portion of the anodes may lower current density in that region. Likewise, turning on the portion of anodes will increase the current density in that region.
