Patent ID: 7432588

Claim:
A semiconductor device comprising: a leadframe having an island portion, the island portion having first and second opposing surfaces; first and second semiconductor chips each having a top surface and a back surface, each said top surface having a plurality of bonding pads arranged on a peripheral area thereof, the back surfaces of the first and second semiconductor chips being mounted to the first and second surfaces of the island portion, respectively; and a mold resin covering the first and second semiconductor chips; wherein the first and second semiconductor chips are constructed so that in plan view, if the first and second semiconductor chips were arranged on respective said surfaces of the island portion with perimeters of the first and second semiconductor chips aligned, the bonding pads of the first semiconductor chip would overlap the bonding pads of the second semiconductor chip; wherein the first and second semiconductor chips are arranged respectively on the first and second surfaces of the island portion so that, in plan view, none of the bonding pads of the first semiconductor chip overlaps any of the bonding pads of the second semiconductor chip.
