Abstract:
A plastic mold type semiconductor device comprising:a bed of a lead frame;a semiconductor chip having electrodes on the periphery of an upper surface thereof, said semiconductor chip being supported by the bed and having an edge defining one end of said semiconductor chip, said edge being substantially perpendicular with respect to said upper surface;a mold body in which said semiconductor chip is sealed, said mold body having an interior region defined within said mold body, said interior region being further defined by an upper region above said semiconductor chip and a lower region below said semiconductor chip, said upper region being further defined by a first upper region and a second upper region contiguous with said first upper region and abutting said first upper region along a plane passing through said edge of said semiconductor chip, wherein said plane is perpendicular with respect to said upper surface of said semiconductor surface, and said first upper region extends exteriorly with respect to said semiconductor chip and said second upper region extends above said semiconductor chip;leads, each having an outer lead portion projecting from said mold body and an inner lead portion extending into the upper region of said mold body spatially apart from the upper surface of said semiconductor chip within said mold body, said inner lead portion extending through both said first upper region and said second upper region; andbonding wires for connecting said electrodes of said semiconductor chip to corresponding points on said inner lead portions, said points being located in said first upper region in a location exterior of said semiconductor chip and spatially apart from said semiconductor chip.
