Patent ID: 7247949

Claim:
A semiconductor device, comprising: a first semiconductor chip having a first surface with a first region and a second region, the chip additionally having a first circuit formed in the first region and a first electrode on the first region that is electrically connected to the first circuit, the first semiconductor chip further having a second electrode on the second region, the second electrode being electrically connected to the first electrode; a second semiconductor chip that is smaller than the first chip, the second chip having a second surface where a second circuit is formed and having a third electrode that is electrically connected to the second circuit, the second chip being stacked on the first chip and the third electrode being electrically connected to the first electrode; resin disposed between the first and second chips and on the first chip in a region not covered by the second chip, wherein the resin disposed between the first and second chips has a thickness that is the same as the distance between the first and second chips so as to fill a space between the first and second chips; wherein the second electrode has an end surface that is even with a surface of the resin disposed in the region not covered by the second chip, wherein the second electrode has a height that is smaller than the distance between the first and second chips, and wherein a protruding electrode is attached to the end surface of the second electrode.
