Abstract:
A semiconductor device comprising:a die pad;a semiconductor element mounted on the die pad;a first lead having an inner end connected to the die pad;a second lead having an inner end electrically connected to the semiconductor element via a wire; anda molding resin integrally encapsulating the die pad, the semiconductor element, an inner portion of the first lead and an inner portion of the second lead,wherein:at least part of the bottom of the die pad is exposed on the bottom of the molding resin,at least part of the bottom of the first lead is exposed on the bottom of the molding resin,at least part of the bottom of the second lead is exposed on the bottom of the molding resin,the exposed part of the die pad is substantially flush with the exposed part of the second lead at a first level,the die pad includes a thickness-reduced side portion protruding substantially in parallel to a mounting plane of the die pad, the thickness-reduced side portion being covered with the molding resin,the inner portion of the second lead includes a bent portion for bending the inner end of the second lead in a direction from the bottom toward the upper surface of the second lead, anda distance between the first level and a bottom of the inner end of the second lead is equal to or larger than a distance between the first level and a bottom of each of the thickness-reduced side portions.
