Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:(a) providing a frame body comprised of metal, the frame body having an opening, a film base material arranged in the opening and fixed to the frame body, the film base material having a resin sealing area, a peripheral area and a plurality of electrodes formed on the resin sealing area, wherein the peripheral area is interposed between the resin sealing area and the frame body; (b) providing a semiconductor chip having a main surface, a rear surface and a plurality of electrodes formed on the main surface; (c) fixing the rear surface of the semiconductor chip on the resin sealing area; (d) electrically connecting the plurality of electrodes of the semiconductor chip with the plurality of electrodes of the film base material via a plurality of wires; (e) forming a first resin sealing body on the resin sealing area, wherein the first resin sealing body seals the semiconductor chip, the plurality of wires and the plurality of electrodes of the film base material, the first resin sealing body being formed to have a space between the periphery of the first resin sealing body and the frame body; and (f) dividing the film base material at the resin sealing area from the film base material at the peripheral area.
