ABSTRACT:
A semiconductor device includes: 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 a raised electrode, the circuitry side of the first chip facing the 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 electrode on the circuitry side thereof. The non-circuitry sides of the first and second semiconductor chips are secured to each other. The external electrode of the second semiconductor chip is connected to the wiring board via a metal fine wire. The external and raised electrodes are so disposed as not to overlap each other as viewed vertically downward from over the principal surface of the wiring board.
