  • Patent number: 9589905
    Abstract: A semiconductor package includes a substrate, a chip disposed over a top surface of the substrate, an electromagnetic interference (EMI) shielding layer disposed over the substrate such that the EMI shielding layer surrounds the chip, a ground pad disposed in the substrate to contact a bottom surface of the substrate, and a test pad disposed in the substrate to contact the bottom surface of the substrate and spaced apart from the ground pad. A method of testing the semiconductor package is performed using a loop circuit to which a current is applied, the loop circuit being formed by electrically coupling the ground pad, the EMI shielding layer, and the test pad.
