Abstract
Provided is a semiconductor device capable of preventing a semiconductor chip from being damaged by any sharp burrs of a metallic shielding plate. The semiconductor device includes a semiconductor chip and a metallic shielding plate provided on a circuit surface of the semiconductor chip. The metallic shielding plate is disposed in such a manner that a second surface of a shielding plate body is directed towards the circuit surface of the semiconductor chip, and burrs are positioned contiguous to the second surface of the shielding plate body. At distal ends of the burrs, cutting burrs are formed in a direction orthogonal to the second surface. The sharp burrs extend in a direction opposite to the semiconductor chip, so that the sharp burrs are prevented from damaging the circuit surface of the semiconductor chip.
