Patent ID: 7307339

Claim:
A semiconductor device comprising: a substrate on which a plurality of leads are formed; and a semiconductor chip mounted on the substrate in such a manner that a surface of the semiconductor chip having a plurality of electrodes faces the substrate, wherein each of the plurality of leads includes a first portion that is bonded to one of the plurality of electrodes and a second portion that extends outward from an inner side of a region in the substrate that overlays the semiconductor chip; the second portion is entirely adhered to the substrate and curved; the plurality of electrodes include first electrodes which are arranged along one edge of the semiconductor chip and disposed on a portion of the semiconductor chip except for the center of the edge; the plurality of leads include first leads which are disposed so as to intersect the edge; and the first portion of each of the first leads is disposed on corresponding one of the first electrodes at a position displaced from the center of the corresponding one of the first electrodes in a direction parallel to the edge and toward the center of the edge.
