Abstract

A semiconductor part includes a resin package and an exposed portion exposed from a bottom surface of the resin package. The exposed portion has a first diagonal line perpendicular to both first and third sides of the package as viewed from the bottom surface. The exposed portion also has a second diagonal line perpendicular to both the second fourth side in the bottom view. A first lead terminal portion opposes the exposed portion and has a first shape in the bottom view. A second lead terminal portion, also opposing the exposed portion, has a second shape in the bottom view. A third lead terminal portion opposing the exposed portion, also has the second shape in the bottom view. A fourth lead terminal portion, similarly opposed to the exposed portion, likewise has the second shape in the bottom view.
