Patent ID: 7535091

Claim:
A multichip stacking structure comprising: a chip carrier; a plurality of semiconductor chips stacked on the chip carrier in a stepped manner that an overlying chip mounted on an underlying chip of the plurality of semiconductor chips has a suspended portion free of being in contact with the underlying chip; and a bump mounted on the chip carrier at a position corresponding to a suspended side of the stacked semiconductor chips where the suspended portion of the overlying chip is located, at least a portion of the bump being located right below the suspended portion of the overlying chip, the bump being free of contact with the semiconductor chips and free of electrical connection with the chip carrier, and positioned on the chip carrier to prevent separation of the semiconductor chips during encapsulation, wherein the semiconductor chips are electrically connected to the chip carrier via a plurality of bonding wires, and the bonding wires are parallel to a direction of a mold flow of an encapsulating resin injected through a mold gate.
