Abstract:
1. A semiconductor device, comprising: a lead frame having inner connecting portions and outer connecting portions, at least a part of a lead terminal portion including the inner connecting portions and the outer connecting portions has a cross-section, that is taken along a plane that is perpendicular to the longitudinal direction of the lead terminal portion, in a shape of an inverted trapezoid; a semiconductor chip having electrodes on a surface thereof; metal wires for electrically connecting the electrodes on the semiconductor chip and the inner connecting portions of the lead frame; a sealing resin for sealing the inner connecting portions of the lead frame, the semiconductor chip and the metal wires therein, and at the same time exposing the outer connecting portions of the lead frame at a bottom surface thereof; and an inner connecting portion sealing resin for covering the inner connecting portion at the bottom side of the sealing resin; wherein the inner connecting portion sealing resin exists beneath the connecting portion of the inner connecting portion with the metal wires; a head end of the outer connecting portion is substantially in a same plane with a side surface of the sealing resin, the head end of the outer connecting portion having no chipped portion.
