Patent ID: 7202565

Claim:
A semiconductor device comprising: multiple kinds of interlayer insulating films formed on a semiconductor substrate and having different elastic moduli, respectively; a metal pad for wire bonding arranged on said multiple kinds of interlayer insulating films; the multiple kinds of interlayer insulating films including a first interlayer insulating film having the lowest elastic modulus among said different elastic moduli and having an opening located under said metal pad; the multiple kinds of interlayer insulating films including a second interlayer insulating film having an elastic modulus larger than the lowest elastic modulus, being underlying and in contact with said first interlayer insulating film; and a metal interconnection layer having an elastic modulus larger than the lowest elastic modulus, arranged under said metal pad, filling the opening in said first interlayer insulating film, and being in contact with said second interlayer insulating film at a lower surface of the metal interconnection layer, wherein the metal interconnection layer and the second interlayer insulating film are arranged immediately under the metal pad, and the first interlayer insulating film is not arranged under the metal pad by arranging the metal pad in an area of the opening.
