Abstract:
A semiconductor device comprising:a wiring board; a first semiconductor chip, which has a circuitry side and a non-circuitry side that face each other vertically and which is electrically connected to the wiring board via raised electrodes, the circuitry sides of the first semiconductor chip facing a principal surface of the wiring board; and a second semiconductor chip, which has a circuitry side and a non-circuitry side that face each other vertically and which includes an external electrodes on the circuitry side thereof, wherein the non-circuitry side of the first and second semiconductor chip are secured to each other, and wherein each of the external electrodes is connected to the wiring board via metal fine wires, and wherein the external electrodes are so disposed as not to overlap with the raised electrodes, and wherein at least one of the side faces of the first semiconductor chip and at least one of the side faces of the second semiconductor chip are almost aligned with each other.
