Abstract:
1. A semiconductor package comprising: a lead frame including a chip mounting portion and a terminal portion, said lead frame having one side and another side opposite to the one side; a semiconductor chip, which is mounted on the chip mounting portion on the one side and connected to the terminal portion; a through groove provided on a side surface of the terminal portion so as to penetrate the terminal portion from the one side to the another side in a thickness direction of the terminal portion; a lid portion covering an end portion of the through groove on the one side; and a resin portion sealing the semiconductor chip and a gap between the chip mounting portion and the terminal portion, wherein an end surface of the terminal portion is coated by a plating film at the another side, wherein the terminal portion has a side surface that is exposed on the resin portion, said side surface having an inner side surface of the through groove that is coated by the plating film, and another part that is not coated by the plating film, wherein surfaces of the chip mounting portion and the terminal portion facing the another side, a side surface of the lid portion facing an outside of the semiconductor package, and a part of the lid portion exposed to the inner side surface of the through groove are exposed on the resin portion, and wherein the through groove is formed only in the terminal portion.
