Patent ID: 8373264

Claim:
A packaged semiconductor module having an integrated electromagnetic interference shield comprising: a substrate having a ground plane; an electronic device mounted on a surface of the substrate; a plurality of wirebond springs disposed about the electronic device and electrically coupled to the ground plane, each of the plurality of wirebond springs including a loop of wire having a ball bond disposed on the surface of the substrate, a zone of inflection, a crest, a convex region extending between the zone of inflection and the crest, the zone of inflection being between the convex region and the ball bond, a sloping tail region having an end coupled to the substrate, and a substantially flat region extending between the crest and the sloping tail region; a mold compound covering the electronic device and at least partially covering the plurality of wirebond springs; and a conductive layer disposed on a top surface of the mold compound and electrically coupled to at least some of the plurality of wirebond springs, the plurality of wirebond springs, the conductive layer, and the ground plane together forming the integrated electromagnetic interference shield.
