Patents by Inventor Ming Xi Chan

Ming Xi Chan 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: 6114227
    Abstract: This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition or transport polymerization. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount and the quality of the film that can be deposited without requiring the system to be shut down for cleaning.
    Type: Grant
    Filed: March 29, 1999
    Date of Patent: September 5, 2000
    Assignee: Quester Technology, Inc.
    Inventors: David Leksell, Ming Xi Chan, Joseph P. Ellul, Jeanne L. Luce, David T. Ryan, Iqbal A. Shareef, Chung J. Lee, Stephen M. Campbell, Giovanni Antonio Foggiato
  • Patent number: 6079353

New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount of thin film, and the quality of the film which can be deposited without requiring the system to be shut down. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.
