Abstract:
A semiconductor device comprising:a wiring substrate having a through opening, and lands, fingers, routing, through holes on a first face and a second face of said wiring substrate, a first semiconductor chip having center pads centrally located on a main face of said first semiconductor chip, wherein the second face of said wiring substrate and the main face of said first semiconductor chip are bonded to each other so that the through opening of said wiring substrate surrounds said center pads; a second semiconductor chip having pads, wherein a back face of said first semiconductor chip and a back face of said second semiconductor chip are fixed to each other using a bonding material; metal wires passing through the through opening in said wiring substrate and connecting said center pads on said first semiconductor chip to fingers corresponding to said center pads on the first face of said wiring substrate, and metal wires connecting said pads on said second semiconductor chip to fingers corresponding to said pads on the second face of said wiring substrate; and sealing resin encapsulating said metal wires, said first and second semiconductor chips, and filling the through opening.
