Patent ID: 7812429

Claim:
A semiconductor device comprising: a chip mounting portion including a chip supporting surface; a suspension lead supporting the chip mounting portion; a semiconductor chip having a quadrilateral principal surface, and provided with a first electrode pad arranged at a middle portion of a first side of the principal surface and with a second electrode pad arranged closer to a corner portion of the first side than the first electrode pad, wherein the semiconductor chip is mounted over the chip supporting surface of the chip mounting portion; a first lead provided correspondingly to the middle portion of the first side of the semiconductor chip; a second lead arranged closer to the suspension lead than the first lead; a first wire electrically connecting the first electrode pad and the first lead; a second wire electrically connecting the second electrode pad and the second lead; and a third wire electrically connecting the second electrode pad and the suspension lead, wherein a plurality of electrode pads including the first electrode pad and the second electrode pad are formed over the principal surface of the semiconductor chip, wherein a plurality of leads including the first lead and the second lead are arranged around the chip mounting portion, wherein a plurality of wires including the first wire and the second wire are provided, wherein the first wire is shorter than the second wire, wherein the suspension lead has a first portion connected with the chip mounting portion and a second portion connected with the first portion, wherein a width of the first portion of the suspension lead is broader than a width of the second portion of the suspension lead, wherein the second portion of the suspension lead is disposed between two edge leads in the plurality of leads, and wherein the third wire is electrically connected with the first portion of the suspension lead.
