The method includes implanting stud bumps on the fingers of the carrier and electrically connecting the chip and the carrier by copper wires with one ends of the copper wires being bonded to bond pads of the chip and the other ends of the copper wires being bonded to the stud bumps on the carrier. The implanted stud bumps on the carrier improve bondability of the copper wires to the carrier and thus prevent stitch lift. With good bonding, residues of copper wires left behind after a bonding process have even tail ends and uniform tail length to enable fabrication of solder balls of uniform size, thereby eliminating a conventional step of implanting stud bumps on the bond pads of chips and preventing ball lift from occurring.

  • Patent number: 7364947
    Abstract: In an electronic component comprising a semiconductor chip packaged in a molded part from which the lead terminals of the semiconductor chip project, a main cutting notch is formed on the obverse surface of each lead terminal before molding the molded part while leaving unnotched portions adjoining both ends of the main notch. Then, each lead terminal is cut at the main notch after molding the molded part, thereby making fewer and smaller cutting burrs occurring at the cut faces.

    Abstract: An integrated circuit device comprising an integrated circuit die having a plurality of bond pads that are selectively connected to a plurality of inner leads of a leadframe. At least two bond pads are connected to at least one of the inner leads, and/or at least two inner leads are connected to at least one of bond pads with a single bond wire. A single bond wire is ball or wedge bonded to a first bond pad or inner lead and subsequently wedge bonded to one or more second bond pads or inner leads, then it is connected to a third or last bond pad or inner lead. The single bond wire requires only one connection area at each of the bond pad(s) and/or inner lead(s). The bond pad(s) of the die and/or inner lead(s) of the leadframe are thereby electrically connected together by the single bond wire.

  • Patent number: 7323361
    Abstract: A package system for integrated circuit (IC) chips and a method for making such a package system. The method uses a solder-ball flip-chip method for connecting the IC chips onto a lead frame that has pre-formed gull-wing leads only on the source/gate side of the chip. A boschman molding technique is used for the encapsulation process, leaving exposed land and die bottoms for a direct connection to a circuit board. The resulting packaged IC chip has the source of the chip directly connected to the lead frame by solder balls. As well, the drain and gate of the chip are directly mounted to the circuit board without the need for leads from the drain side of the chip.
