Patents by Inventor Zhenxu Pang

Zhenxu Pang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8518224
    Abstract: The present invention provides a plating apparatus with multiple anode zones and cathode zones. The electrolyte flow field within each zone is controlled individually with independent flow control devices. A gas bubble collector whose surface is made into pleated channels is implemented for gas removal by collecting small bubbles, coalescing them, and releasing the residual gas. A buffer zone built within the gas bubble collector further allows unstable microscopic bubbles to dissolve.

  • Patent number: 8383429
    Abstract: The present invention provides an apparatus and method for rapid and uniform thermal treatment of semiconductor workpieces in two closely arranged thermal treatment chambers with a retractable door between them. The retractable door moves in between two thermal treatment chambers during heating or cooling process, and additional heating and cooling sources are provided for double-side thermal treatment of the semiconductor workpiece.

  • Publication number: 20110073469
    Abstract: A electrochemical deposition system which has a 3-D stacked architecture comprises a factory interface for receiving semiconductor wafers, a mainframe comprising a mainframe transfer robot and a plurality of wafer holder assemblies which disposed on the top thereof, a plurality of electroplating cells disposed within the mainframe, a plurality of cleaning cells disposed within the mainframe and located below the electroplating cells, a plurality of thermal treatment chambers disposed in between the mainframe and the factory interface, and a fluid distribution system fluidly connected to the electroplating cells and the cleaning cells, wherein the mainframe transfer robot transfers the semiconductor wafer from the factory interface and within the electroplating cells, the cleaning cells, and the thermal treatment chambers. As a result, the system of the present invention is expandable to accommodate newly-added processing units without overmuch increased footprint.
