Patent ID: 7777312

Claim:
A semiconductor device comprising: a semiconductor chip having a first major surface and a second major surface opposite to the first major surface, and having a plurality of electrical connection pads disposed over the first major surface; a tab over which the semiconductor chip is mounted, the tab having an upper surface and a bottom surface opposite to the upper surface, the upper surface facing the second major surface of the semiconductor chip; a plurality of leads disposed around the tab, each of the leads comprising a first portion and a second portion integrally connected to the first portion, the second portions extending inwardly from the first portions toward the tab, respectively; a plurality of suspension leads integrally connected to the tab; a plurality of conductive wires electrically coupling the electrical connection pads and the plurality of leads, respectively; and a resin material covering the semiconductor chip, the conductive wires, and parts of the leads, the resin material having a front surface and a rear surface opposite to the front surface, the front surface in a plan view is comprised of a rectangular shape having a pair of first sides and a pair of second sides intersecting with the first sides wherein the first portion of each of the leads is partially exposed from the rear surface of the resin material; wherein the second portion of each of the leads has a thickness smaller than that of the first portion of each of the leads; wherein the second portion of each of the leads is positioned inside the resin material without being exposed from the rear surface of the resin material; wherein the plurality of leads includes a first lead arranged along one of the first sides of the resin material and a second lead arranged along one of the second sides of the resin material; wherein the second portion of each of the first lead and the second lead extends obliquely from the first portion of each of the first lead and the second lead, respectively, in a plan view, wherein each of the suspension leads has a thickness smaller than that of the first portion of each of the leads; wherein each of the suspension leads is positioned inside the resin material without being exposed from the rear surface of the resin material; wherein a first suspension lead of the suspension leads is extended from a central portion of the resin material to a corner portion of the resin material in a plan view; and wherein the first suspension lead of the suspension leads is located between and adjacent to the first lead and the second lead in a plan view.
