Patents by Inventor Robert G. Hieronymi

Robert G. Hieronymi 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: 6395146
    Abstract: A cathode assembly includes a monolithic target having a first surface and a center region. In addition, a sculpted section is formed in the first surface, and the sculpted section is generally recessed from the first surface and extends around the center in a racetrack configuration. The racetrack has a concentric centerline, and the sculpted section preferably is generally symmetric about the centerline. A magnetic field generator is disposed adjacent to the target and produces a magnetic field having an in-plane component. The magnetic field generator is tuned so that a distribution of the magnitude of the in-plane component in a direction transverse to the centerline at a point along the racetrack is characterized by two peaks that have a generally equal magnitude.

  • Patent number: 4428816
    Abstract: A cathode assembly for use in a magnetron sputtering system, the system having a cathode assembly with parallel elongated target segments which are formed substantially of a material which is desired to be sputter-deposited onto a substrate. The elongated target segments are each provided with a material removal surface which is inclined toward the other segment with respect to the plane of the substrate. Such inclination permits the material which is removed from the target bars to be focused onto a relatively narrow area, thereby improving the efficiency of the sputtering operation and reducing machine down-time for cleaning and vacuum pumping. End target segments are provided for improving the efficiency of film deposition near the ends of the elongated bars. The end target segments are provided with material removal surfaces which are also inclined, and connect with the elongated target segments to form a rectangular frame arrangement.
