Patents by Inventor Doeg-Jung Kim

Doeg-Jung Kim 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: 7086132
    Abstract: Disclosed are a method for assembling a polishing while inspecting for air leakage in the polishing head and an apparatus for performing the same. By the present invention, a polishing head may be tested for air leakage at each assembly step thereof, so that the polishing head may be assembled free of air leakage, thereby reducing testing time of the polishing head, and failure of the polishing head due to air leakage may be prevented. The apparatus includes a housing supporting the polishing head and having coupling lines coupled with ends of tubes provided in the assembled polishing head, or the polishing head being assembled. A pneumatic pressure regulating section selectively supplies positive pressure or vacuum to the tubes through the coupling lines. A sensor section detects the pressure and level of vacuum in the tubes. A determining section determines if there is air leakage in the polishing head.
