Patents by Inventor Hideo Sonohara

Hideo Sonohara 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: 8174123
    Abstract: A semiconductor integrated circuit according to an exemplary embodiment of the present invention includes an I/O buffer provided in a semiconductor chip, single-layer pads, and multilayer pads. The single-layer pads are formed above the I/O buffer. The multilayer pads are formed above the I/O buffer separately from the single-layer pads. The single-layer pads are pads dedicated to bonding, and the multilayer pads are pads on which both probing and bonding are performed.
    Type: Grant
    Filed: December 24, 2009
    Date of Patent: May 8, 2012
    Assignee: Renesas Electronics Corporation

  • Patent number: 7541683
    Abstract: A semiconductor integrated circuit device of improved wireability, fewer number of wiring layers and strengthened power supply includes a plurality of power pads placed on a semiconductor chip and a plurality of signal pads placed on the semiconductor chip and configured to have a width less than that of the power pads. The signal pads and the power pads are placed in the uppermost wiring layer among a plurality of wiring layers. Signal wiring connecting I/O cells and signal pads is disposed in the uppermost wiring layer. First power wiring electrically connecting the I/O cells and first power pads is disposed in the uppermost wiring layer. Second power wiring connecting internal circuits and second power pads is disposed in the uppermost wiring layer.

  • Patent number: 7263681
    Abstract: A semiconductor integrated circuit device includes macros and area I/Os. The macros are arranged in optional locations of a first empty area of a gate area in a center portion of a chip, respectively. Each of the area I/Os contains a plurality of area I/O buffers, and is arranged in an optional location of a second empty area of a total area of the gate area and a buffer area in a circumferential portion of the chip. A first macro of the macros is connected with a specific one of the area I/Os. Here, the specific area I/O may be related to the first macro and be arranged in relation to a location for the first macro to be arranged.
