Patents by Inventor Henan Hao

Henan Hao 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: 7025862
    Abstract: An apparatus for providing an electrical bias to a substrate in a processing system is described. The apparatus generally includes a conductive annular body defining a central opening. The conductive annular body may have a substrate seating surface adapted to receive the substrate and a plurality of scallops formed on a surface opposing the substrate seating surface. A plurality of electrical contacts may be formed on the substrate seating surface opposite the plurality of scallops. The electrical contacts may be adapted to engage a plating surface of the substrate.
    Type: Grant
    Filed: October 22, 2002
    Date of Patent: April 11, 2006
    Assignee: Applied Materials
    Inventors: Harald Herchen, Henan Hao, Celina M. Esteban, Timothy R. Webb, Son N. Trinh

  • Publication number: 20040069651
    Abstract: Method and apparatus for electrodepositing a metal onto a substrate. An oxide treatment process is performed on a substrate prior to making electrical contact between a seed layer of the substrate and a conductive contact element which provides a current. In one embodiment, the pressure at the interface between the seed layer and the conductive contact element is controlled to avoid detrimentally affecting a material(s) of the substrate.

  • Patent number: 6267853
    Abstract: The present invention provides an electro-chemical deposition system that is designed with a flexible architecture that is expandable to accommodate future designs and gap fill requirements and provides satisfactory throughput to meet the demands of other processing systems. The electro-chemical deposition system generally comprises a mainframe having a mainframe wafer transfer robot, a loading station disposed in connection with the mainframe, one or more processing cells disposed in connection with the mainframe, and an electrolyte supply fluidly connected to the one or more electrical processing cells.
