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