Hyeon Woo Ha 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: 7737477
    Abstract: A CMOS image sensor and a method for manufacturing the same improve light-receiving efficiency and maintain a margin in the design of a metal line. The CMOS image sensor includes a transparent substrate including an active area having a photodiode region and a transistor region and a field area for isolation of the active area, a p-type semiconductor layer on the transparent substrate, a photodiode in the p-type semiconductor layer corresponding to the photodiode region, and a plurality of transistors in the p-type semiconductor layer corresponding to the transistor region.
    Type: Grant
    Filed: September 23, 2008
    Date of Patent: June 15, 2010
