Patents by Inventor Hong Gap Chua

Hong Gap Chua 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: 8722545
    Abstract: A method of forming a transistor is disclosed, in which gate-to-substrate leakage is addressed by forming and maintaining a conformal oxide layer overlying the transistor gate. Using the method disclosed for an n-type device, the conformal oxide layer can be formed as part of the source-drain doping process. Subsequent removal of residual phosphorous dopants from the surface of the oxide layer is accomplished without significant erosion of the oxide layer. The removal step uses a selective deglazing process that employs a hydrolytic reaction, and an acid-base neutralization reaction that includes an ammonium hydroxide component.
    Type: Grant
