In the resin-encapsulated semiconductor device of the present invention, the die pad is bonded to the upper surface of the first semiconductor chip, and the second semiconductor chip smaller than the first semiconductor chip is bonded to the upper surface of the die pad. The respective electrodes of the first semiconductor chip and the second semiconductor chip are electrically connected to the inner leads of the lead frame. According to this resin-encapsulated semiconductor device, two semiconductor chips are adhered to both sides of the die pad and resin-encapsulated, so that the device is multi-chiped without increasing the occupied area and the integration density of the integrated circuit of the device is increased. be able to. And
Since the semiconductor chip is adhered to both surfaces of the die pad, and the TAB tape is used in this state to connect the electrode and the inner lead and resin sealing can be performed, the semiconductor chip can be assembled in a stable state. Further, since the inside of the resin-sealed semiconductor device can the electrical connection between the two semiconductor chips, to reduce the number of wiring film of a circuit board for mounting the resin-sealed semiconductor device, increase the integration density Rukoto Will be possible.
