Patent ID: 7285854

Claim:
A semiconductor device comprising: a semiconductor chip having a chip electrode; an interconnection electrode; a first conducting ball bonded to a first bonding point on a first electrode, which is one of the chip electrode and the interconnection electrode; a first conducting wire, one end of which is ball-bonded to a second bonding point on a second electrode, and the other end of which is stitch-bonded to the first conducting ball, the second electrode being the other of the chip electrode and the interconnection electrode; a second conducting ball bonded to the first conducting ball so that the first conducting ball is sandwiched between the second conducting ball and the first electrode; and a second conducting wire, one end of which is ball-bonded to a third bonding point on the second electrode, and the other end of which is stitch-bonded to the second conducting ball, wherein the second conducting wire extends generally in the same direction as the first conducting wire does, and wherein the third bonding paint is further from the first bonding point than the second bonding point is.
