ABSTRACT:
There is provided a semiconductor device having a very thin, highly reliable semiconductor package and a method of easily manufacturing the semiconductor apparatus. The method comprises a first step of coating and melting a thermosetting resin in a mold for resin sealing, while keeping the mold at a predetermined temperature, the mold being divided into an upper mold and a lower mold, a second step of fixing within the mold a lead frame supporting a semiconductor chip, and a third step of applying a pressure on the mold and compression-molding the resin, thus forming a package.
