Patents by Inventor Soon Tak KWON

Soon Tak KWON 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: 9865677
    Abstract: Provided is a super junction semiconductor device. The super junction semiconductor device includes a vertical pillar region located in an active region and horizontal pillar regions located in a termination region that are connected with each other while simultaneously not floating the entire pillar region in the termination region. Thus, a charge compensation difference, generated among pillar regions, is caused to be offset, although the length of the termination region is relatively short.
    Type: Grant
