Abstract:
1. A semiconductor device, comprising: (a) a wiring board; (b) a semiconductor chip mounted over the wiring board; (c) a sealing body formed over the wiring board so as to cover the semiconductor chip; and (d) a shield film formed over a surface of the sealing body and electrically coupled to a reference wiring line formed over the wiring board to supply a reference potential, wherein the surface of the sealing body is formed with a product identification mark having a recessed shape for identification of a product and a plurality of peeling prevention marks, each having a recessed shape, for preventing the shield film from peeling from the surface of the sealing body, wherein a product-identification-mark formation region where the product identification mark is disposed and a peeling-prevention-mark formation region where the peeling prevention marks are disposed are different regions, and wherein the peeling-prevention-mark formation region is formed so as to surround the product-identification-mark formation region when viewed in plan view.
