Patent ID: 7298045

Claim:
A semiconductor device, comprising: a first semiconductor element that includes a first face and a second face, the first semiconductor element having a first electrode the first face thereof; a second semiconductor element that includes a first face and a second face, the second semiconductor element having an outer diameter dimension formed larger than that of the first semiconductor element, the first face of the second semiconductor element being bonded to the second face of the first semiconductor element, and having a second electrode on an outer perimeter of the first face; a wiring substrate that includes a first face and a second face, the wiring substrate having a third electrode joined to the first electrode of the first semiconductor element by flip-chip bonding, the third electrode being on the second face of the wiring substrate; a fine metal wire connecting a fourth electrode the outer perimeter of the first face of the wiring substrate and the second electrode of the second semiconductor element by wire bonding; and an insulating sealing resin for sealing a periphery of the first semiconductor element and a wiring portion of the fine metal wire, between the second semiconductor element and the wiring substrate, wherein a sealing fill region for the sealing resin having substantially the same external dimensions of the second semiconductor element.
