Abstract:
A semiconductor device comprising a semiconductor chip, a chip-mounting internal lead for mounting the semiconductor chip thereon, chip-connecting internal leads connected directly to an upper surface of the semiconductor chip, and a rectangular resin package housing the semiconductor chip and the internal leads,wherein the chip-mounting internal lead includes an end which is rectangular or substantially rectangular and extends lengthwise of the resin package, wherein the resin package includes a pair of side surfaces spaced apart from each other in a longitudinal direction of the resin package, wherein the end of the chip-mounting lead includes a pair of edges spaced apart from each other in the longitudinal direction of the resin package, wherein each of the edges of the chip-mounting lead is closer to a corresponding one of the side surfaces of the resin package than to the semiconductor chip, and wherein a surface area of the chip-mounting lead is no less than 50% of a bottom area of the resin package.
