Abstract:
1. A semiconductor device comprising: a first suspension lead; a second suspension lead intersecting with the first suspension lead; a die pad comprised of a part of the first suspension lead, a part of the second suspension lead, and an intersection point of the first suspension lead and the second suspension lead; a first adhesive tape arranged on said part of the first suspension lead and said intersection point, wherein a planar shape of the first adhesive tape is a rectangular shape; a plurality of second adhesive tapes arranged on said part of the second suspension lead, wherein the plurality of second adhesive tapes are not arranged on the intersection point used to comprise the die pad to thereby avoid overlapping the first adhesive tape with the second adhesive tape, wherein a planar shape of each of the plurality of second adhesive tapes is a rectangular shape, wherein a first one of the second adhesive tapes is separated from a second one of the second adhesive tapes by the first adhesive tape; a semiconductor chip disposed over the die pad through the first adhesive tape and the plurality of second adhesives, the semiconductor chip having a main surface, a rear surface opposed to the main surface and mounted on the first adhesive tape and the plurality of second adhesives, and a plurality of surface electrodes formed on the main surface; a plurality of inner leads arranged around the semiconductor chip; a plurality of wires electrically connected the plurality of surface electrodes of the semiconductor chip with the plurality of inner leads respectively; a molding resin sealing the die pad, the semiconductor chip and the plurality of wires; and a plurality of outer leads respectively connected to the plurality of inner leads and protruding from the molding resin, wherein each of the first and second adhesive tapes is comprised of a base material and an adhesive layer.
