Abstract:
1. A semiconductor device comprising: a first lead frame including an upper surface and a lower surface spaced from each other in a thickness direction; a second lead frame spaced apart from the first lead frame in a first direction, the second lead frame including an upper surface and a lower surface; a semiconductor element connected to both the first lead frame and the second lead frame; and a case covering a part of each of the first lead frame and the second lead frame; wherein the first lead frame includes a first exposed portion provided with an upper surface and a lower surface that is exposed from the case, the second lead frame includes a second exposed portion provided with an upper surface and a lower surface that is exposed from the case, the first lead frame includes a first thin extension smaller in thickness than the first exposed portion, the first thin extension extending from the first exposed portion in a second direction perpendicular to both the first direction and the thickness direction, the second lead frame includes a second thin extension smaller in thickness than the second exposed portion, the first thin extension includes an upper surface and a lower surface, the upper surface of the first thin extension being flush with the upper surface of the first exposed portion, the lower surface of the first thin extension being covered with the case, and the second thin extension includes an upper surface and a lower surface, the upper surface of the second thin extension being flush with the upper surface of the second exposed portion, the lower surface of the second thin extension being covered with the case.
