  • Patent number: 6847111
    Abstract: In a semiconductor device, a semiconductor chip is mounted on an inner seat body of a heat-dissipating frame mounted on a top surface of a dielectric substrate. Each of multiple bonding wires interconnects electrically one of multiple contact pads on the semiconductor chip and a corresponding one of multiple first conductive contacts on the top surface of the substrate so as to establish electrical connection between the contact pads on the semiconductor chip and multiple second conductive contacts on a bottom surface of the substrate via the first conductive contacts and circuit traces of the substrate. An encapsulant encapsulates the bonding wires, the semiconductor chip, and the inner seat body, a portion of an outer frame body of the heat-dissipating frame, and multiple that interconnect portions interconnecting heat-conductively the inner seat body and the outer frame body.

  • Patent number: 6600216
    Abstract: An improved structure of a pin platform of an integrated circuit having a pin platform body including a chip seat and a plurality of leading plates having their end portions being concentrated on the chip seat and the chip seat being connected to the pin platform body via the connection plate, characterized in that the surrounding of the chip seat is provided with a framing side, and the framing side is connected to a connection plate, and the surface of the chip seat is smaller than the connection surface of the IC to be installed, and the size of the framing side is larger than the size of the connection face of the IC. Therefore, a high performance greenery package is obtained and the ground wire of the IC can be soldered to the framing side, which provides a smooth connection and a communication.
