Abstract:
1. A semiconductor device comprising: a resin package; at least two main leads integrated within the resin package so as to constitute a chip mounting portion; a semiconductor chip mounted on the chip mounting portion; and first and second surface leads each electrically connected to an electrode formed on a surface of the semiconductor chip, wherein: the main leads and the first and second surface leads protrude outward along a bottom surface of the resin package, respectively, and the main leads include a plurality of leads, the plurality of leads each having a larger width than the first and second surface leads or being configured such that the gap therebetween becomes smaller than that between the first and second surface leads in protruding regions of the main leads protruding outward from the resin package, wherein the main leads and the first surface lead and the second surface lead are extended from the resin package outward in parallel to each other.
