Abstract:
1. A method of making a shielded semiconductor device, comprising: providing a first substrate, the first substrate including multiple laminated layers; mounting a plurality of semiconductor die to the first substrate; forming an encapsulant over the semiconductor die and first substrate; forming a dicing channel through the encapsulant between the semiconductor die to expose a flat upper surface of the first substrate, the dicing channel having substantially vertical sidewalls; forming a circular opening through the first substrate and in a region of the flat upper surface that is exposed by the dicing channel; forming a shielding layer over the encapsulant and in the circular opening, the shielding layer covering sidewalls of the circular opening along an entire length of the circular opening; singulating the first substrate to separate the semiconductor die; mounting the first substrate to a second substrate; and forming a metal pillar in the opening to electrically connect the shielding layer to a ground plane disposed in the second substrate.
