Abstract:
1. A semiconductor device comprising: a substrate having a first side and a second side opposite the first side; a first semiconductor chip on the substrate; a second semiconductor chip on the first semiconductor chip, the second semiconductor chip having plural first bonding pads spaced a first distance apart along a third side of the second semiconductor chip facing the first side and plural second bonding pads spaced a second distance apart along a fourth side of the second semiconductor chip opposite the third side, the first side being spaced farther from the third side than the second side is spaced from the fourth side; a plurality of first wires that each directly connect the substrate to respective ones of the first bonding pads, and a plurality of second wires that each directly connect the substrate to respective ones of the second bonding pads, each wire of the plurality of first wires being longer than each wire of the plurality of second wires; and a sealing resin covering the first and second semiconductor chips, the plurality of first wires, and the plurality of second wires, wherein the second semiconductor chip is completely overlapped with the first semiconductor chip in plan view.
