  • Patent number: 7768456
    Abstract: First and second wires are formed so that the further away from a semiconductor chip, the greater the distance between the first and second wires. This prevents currents flowing through the first and second wires from cancelling out each other, and further enables a metallic plate to be disposed as far away from the semiconductor chip as possible. In addition, configuring the metallic plate to have a constant width that is wider than the diameters of the first and second wires results in a wide connection range, thereby ensuring connection even when mounting misalignments occur between the wires and the metallic plate.
