Patents by Inventor Akihito Ishimura

Akihito Ishimura 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: 9136252
    Abstract: A semiconductor device includes a substrate having a first surface, a height adjuster mounted on the first surface of the substrate via a first adhesive layer, a semiconductor chip mounted on the height adjuster via a second adhesive layer, an electronic component mounted on the first surface of the substrate via a third adhesive layer, a bonding wire, and a sealing member. The length of the electronic component in a first direction corresponding to the thickness direction of the substrate is larger than the length of the semiconductor chip in the first direction, and the sum of the lengths of the height adjuster, the second adhesive layer, and the semiconductor chip in the first direction is larger than the length of the electronic component in the first direction.
    Type: Grant

  • Patent number: 7339257
    Abstract: A lead frame has a plurality of first inner leads having distal end portions and parallel to each other, and a plurality of second inner leads having distal end portions opposing the distal end portions of the first inner leads, longer than the first inner leads, and parallel to each other. The semiconductor chip has a plurality of bonding pads arranged along one side of an element formation surface, and is mounted on the surfaces of the plurality of second inner leads using an insulating adhesive. The plurality of bonding wires include first bonding wires which electrically connect the distal end portions of the plurality of first inner leads to some of the plurality of bonding pads, and a plurality of second bonding wires which electrically connect the distal end portions of the plurality of second inner leads to the rest of the plurality of bonding pads.
