Patent ID: 8652880

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) preparing a die pad and a lead frame including a plurality of leads disposed around the die pad; (b) preparing a semiconductor chip having a principal surface and a rear surface opposite to the principal surface, the semiconductor chip including on the principal surface side a plurality of magnetic memory elements and a plurality of bonding pads; (c) mounting the semiconductor chip over the die pad; (d) disposing a magnetic shield material formed of a metal plate over the principal surface of the semiconductor chip so as to cover a region where the magnetic memory elements are formed; (e) electrically coupling the leads to the bonding pads with a plurality of bonding wires; and (f) sealing a part of the respective leads, the bonding wires, the die pad, the semiconductor chip, and the magnetic shield material with a resin body; wherein the magnetic shield material is a magnetic shield material formed by patterning a plate-like magnetic shield material by selective etching, and wherein an area of the die pad is smaller than an area of the semiconductor chip and smaller than an area of the magnetic shield material.
