Bruce David Gittleman 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: 6719886
    Abstract: Ionized Physical Vapor Deposition (IPVD) is provided by a method of apparatus (500) particularly useful for sputtering conductive metal coating material from an annular magnetron sputtering target (10). The sputtered material is ionized in a processing space between the target (10) and a substrate (100) by generating a dense plasma in the space with energy coupled from a coil (39) located outside of the vacuum chamber (501) behind a dielectric window (33) in the chamber wall (502) at the center of the opening (421) in the sputtering target. A Faraday type shield (26) physically shields the window to prevent coating material from coating the window, while allowing the inductive coupling of energy from the coil into the processing space.
    Type: Grant

    Date of Patent: April 13, 2004
    Assignee: Tokyo Electron Limited

  • Patent number: 6287435

The sputtered material is ionized in a processing space between the target and a substrate by generating a dense plasma in the space with energy coupled from a coil located outside of the vacuum chamber behind a dielectric window in the chamber wall at the center of the opening in the sputtering target. Faraday type shields physically shield the window to prevent coating material from coating the window, while allowing the inductive coupling of energy from the coil into the processing space. The location of the coil in the plane of the target or behind the target allows the target to wafer spacing to be chosen to optimize film deposition rate and uniformity, and also provides for the advantages of a ring-shaped source without the problems associated with unwanted deposition in the opening at the target center.

  • Patent number: 6107195
    Abstract: A method of minimizing intragranular oxidation of TiON and providing a low resistivity film that provides for highly textured metal overlayers. The method provides an in situ diffusion barrier for subsequent high temperature metal deposition or processes. An in situ process eliminates the need for a fortification anneal immediately following the barrier deposition, thus reducing the number of metal processing steps and providing for a more economical process or for subsequent high temperature metal deposition. The surface properties of the TiON allow for improved texture in those metal overlayers as well as low diffusion barrier resistivity.
