  • Patent number: 6355502
    Abstract: A method for making a semiconductor package firstly provides a lead frame having a first surface and a corresponding second surface. The lead frame includes at least a package unit that further includes a die pad, and a plurality of leads disposed on the periphery of the die pad where each of the leads further includes a neck portion. The method then attaches the second surface of the lead frame to a tape, and performs a punching process to cut off the neck portion of the lead so as to form a plurality of conductive blocks disposed independently on the periphery of the die pad. The method further provides a chip having its back surface attach to the first surface of the die pad, and provides electrical connection between the bonding pad and the first surface of the conductive block by using a plurality of bonding wires. Further, the method performs an encapsulating process to encapsulate the chip, the bonding wires, the die pad, and the first surface of the conductive block.
