Abstract:
1. A semiconductor device comprising: a substrate defined by a first side and second side opposite the first side; a first semiconductor chip defined by a third side and a fourth side opposite the third side, the first semiconductor chip being mounted over the substrate so the third and fourth sides face the first and second sides, respectively; a second semiconductor chip defined by a fifth side and a sixth side opposite the fifth side, the second semiconductor chip being stacked over the first semiconductor chip so that a distance between the second side and the sixth side is shorter than a distance between the first side and the fifth side; a plurality of first wires electrically coupling the substrate to the second semiconductor chip and extending across the fifth side without contacting the first semiconductor chip; a plurality of second wires electrically coupling the substrate to the second semiconductor chip and extending across the sixth side, each of the second wires being shorter than the first wires; a plurality of third wires electrically coupling the substrate to the first semiconductor chip and extending across the third side, each of the third wires being shorter than the first and second wires; a plurality of fourth wires electrically coupling the substrate to the first semiconductor chip and extending across the fourth side, each of the fourth wires being shorter than the first and second wires, and wherein the plurality of fourth wires is greater in number than the plurality of second wires; a sealing resin covering the first semiconductor chip, the second semiconductor chip, the first wires, the second wires, the third wires, and the fourth wires.
