摘要： Two semiconductor chips are bonded to each other with the rear surfaces of the respective semiconductor chips faced to each other, so that two longer sides of the semiconductor chips may confront the side of leads, and supporting leads are bonded and fixed onto the circuit forming surface of one of the semiconductor chips. The semiconductor chips are further bonded to each other in a state where the positions of the respective semiconductor chips are staggered relative to each other so that electrodes of one semiconductor chip may lie outside the other longer side of the other semiconductor chip, and that electrodes of the second semiconductor chip may lie outside the other longer side of the first semiconductor chip.

Owing to such a construction, the structure of a semiconductor device can be thinned. The semiconductor chips (4), (5) are bonded and fixed to each other in a state where the, positions of the respective semiconductor chips are staggered relatively to each other so that the electrodes (6) of the semiconductor chip (4) may lie outside the other longer latus (5A2) of the semiconductor chip (5), and that the electrodes (6) of the semiconductor chip (5) may lie outside the other longer latus (4A2) of the semiconductor chip (4). Owing to such a construction, the available percentage of the products of the semiconductor device can be heightened.

摘要： A first semiconductor chip (2) is bonded and secured to a second semiconductor chip (3) with a back surface of the first semiconductor chip (2) and a circuit forming surface (3X) of the second semiconductor chip (3) facing each other, and an inner portion of a support lead (6) is bonded and secured to the circuit forming surface (3X) of the second semiconductor chip (3). Such a configuration makes it possible to provide a semiconductor with a reduced thickness.
