Patents by Inventor Chian-Gauh Shih

Chian-Gauh Shih 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: 6593645
    Abstract: A three-dimensional system-on-chip structure comprises a plurality of chips and a plurality of plugs respectively fabricated in the chips. The chips are stacked on top of each other and each includes a periphery circuitry region. A plurality of contact pads is fabricated in each of the periphery circuitry regions. The plugs are formed in the corresponding stacked chips, and are electrically connected to the corresponding contact pads of two of the corresponding chips which are adjacent to each other, or two of the corresponding chips which are not adjacent to each other.
    Type: Grant
    Filed: March 1, 2001
    Date of Patent: July 15, 2003
    Assignee: United Microelectronics Corp.
    Inventors: Chian-Gauh Shih, Hsin-Pang Lu

  • Patent number: 5970011
    Abstract: A power source design for embedded memory uses independent power sources such that a first power source group is linked to the DRAM, a second power source group is linked to the logic unit and a third power source group is linked to the testing mode circuit with input/output ports during the silicon chip stage. In the packaging stage the first power source group, the second power source group and the third power source group are joined together. The design is able to prevent testing errors or instability due to direct current from floating nodes in the silicon chip testing stage, and prevent a potential latch-up problem in the packaging stage.
