Patents by Inventor Everett D. Smith

Everett D. Smith 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: 6500055
    Abstract: A method and apparatus for improving uniformity of the rate of removal of material from the surface of a semiconductor substrate by chemical mechanical polishing. In accordance with the invention, the semiconductor substrate is subjected to a combination of polishing motions, including orbital motion, and at least one additional polishing motion selected from rotational, oscillating, sweeping, and linear polishing motions. The invention also provides an improved method for conditioning polishing pads to provide more uniform conditioning and to extend their useful life span.
    Type: Grant
    Filed: September 18, 2000
    Date of Patent: December 31, 2002
    Assignee: SpeedFam-IPEC Corporation
    Inventors: John A. Adams, Everett D. Smith, Stephen C. Schultz

  • Patent number: 5507732
    Abstract: The present invention is accomplished by providing a catheter manifold (15) having a manifold catheter lumen (115) extending longitudinally therethrough plus a rotationally symmetrical, conically tapering, elastomeric distal seal (65) for gripping the catheter shaft (70), the proximal end of the distal seal (65) having a smaller diameter than the distal end, the distal end of the manifold catheter lumen (115) being conically tapered and sized for a friction fit with the distal seal (65) when the distal seal (65) is inserted into the distal end of the manifold catheter lumen (115), the distal seal (65) having a longitudinally extending distal seal catheter lumen (120).
