Abstract:
1. A semiconductor device comprising: a first semiconductor chip having a first element formation surface provided with first electrodes; and an expanded semiconductor chip including a second semiconductor chip having a second element formation surface and an expanded portion extending outward from at least one side surface of the second semiconductor chip, the expanded semiconductor chip having a surface provided with second electrodes on a same side of the expanded semiconductor chip as the second element formation surface, wherein, the first element formation surface of the first semiconductor chip faces the second element formation surface of the second semiconductor chip, the first element formation surface of the first semiconductor chip provided with the first electrodes faces the surface of the expanded semiconductor chip provided with the second electrodes so that the first electrodes are connected to the second electrodes, and each one of the second electrodes that is connected to an associated one of the first electrodes is located only on the expanded portion.
