Yasuichi Kondo 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: 8878244
    Abstract: Gases for film formation are introduced from a plurality of holes provided at a gas nozzle into a processing chamber of a batch-type CVD film-forming apparatus to cause a turbulence of the gases within the processing chamber. In the state where the chamber is kept at a pressure within an atmospheric and quasi-atmospheric pressure region, a silicon-germanium film is epitaxially grown on a semiconductor wafer placed within the processing chamber. Subsequently, a strained silicon film is epitaxially grown on the silicon-germanium film. Thereafter, a semiconductor element is formed in the semiconductor wafer on which the silicon-germanium film and the strained silicon film have been formed, respectively.
    Type: Grant
