Patent ID: 7948073

Claim:
A three-dimensional package structure, comprising: a carrier substrate; a first die mounted on a first surface of the carrier substrate, wherein the first die comprises first-row bond pads and second-row bond pads located at a central region of the die; a second die directly stacked on the first die, wherein the first die and the second die are mounted on the same side of the carrier substrate; first bond fingers disposed along a first side of the carrier substrate and disposed on the first surface, wherein the second-row bond pads is proximate to the first bond fingers with respect to the first-row bond pads; second bond fingers disposed along a second side of the carrier substrate and disposed on the first surface, wherein the second side is opposite to the first side, and the first-row bond pads is proximate to the second bond fingers with respect to the second-row bond pads; first bond wires bonding, across the second-row bond pads, between the first-row bond pads and the first bond fingers; and second bond wires bonding, across the first-row bond pads, between the second-row bond pads and the second bond fingers.
