  • Patent number: 5684332
    Abstract: A package for a semiconductor die having a plurality of bonding pads about its periphery is provided. The package has a plastic molding encapsulating the semiconductor die. The package also has a plurality of conductive leads with leads having inner and outer portions, the inner portions encapsulated in the molding and arranged substantially in a plane and radially about the semiconductor die with ends displaced from and forming a rectangle with four corners about the die. A bonding wire extends from each of the bonding pads to one of the inner portions of the leads. Bonding wire loop heights of approximately 8 mils are made with a specially designed tip of a capillary tool. The package also has a pair of leads with inner portions at opposite corners of the rectangle, each of the inner portions connected to a pair of bonding wires from a pair of contiguous bonding pads on the die. This double wiring arrangement prevents wire sweep during the injection molding step.
