Abstract:
1. A semiconductor package comprising: a metal die pad, and a plurality of metal leads each radiating away from the die pad, with the die pad and the respective leads each having a first surface and an opposite second surface, and peripheral side surfaces between the first and second surfaces; a semiconductor die coupled to the second surface of the die pad and electrically coupled to the second surface of the leads; and a hardened plastic encapsulant including an exterior planar first surface, an exterior second surface opposite the first surface, and exterior peripheral side surfaces between the first and second surfaces, wherein a lengthwise inner lead portion of each of the leads is embedded in the encapsulant, and a remaining outer lead portion of each of the leads extends outwardly from a respective one of the side surfaces of the encapsulant, the outer lead portion comprising a vertical portion that is approximately perpendicular to the inner lead portion and a foot portion that extends from the vertical portion outwards relative to the encapsulant, wherein the semiconductor die, the second surface and peripheral side surfaces of the die pad, and the second surface and peripheral side surfaces of the inner lead portion of each of the leads are within the encapsulant, wherein the first surfaces of the inner lead portions are exposed in a common plane with the first surface of the encapsulant, and wherein a mounting surface of the outer lead portion of each of the leads is in a plane approximately parallel to, but slightly outward of, the second surface of the encapsulant.
