Abstract:
1. A wiring board with an embedded device and electromagnetic shielding, comprising: a shielding lid; a semiconductor device that is mounted on the shielding lid by an adhesive and includes an active surface with a plurality of contact pads thereon and an inactive surface opposite to the active surface, wherein the active surface faces a first vertical direction away from the shielding lid and the inactive surface faces a second vertical direction toward the shielding lid; a stopper that serves as a placement guide for the semiconductor device and extends from the shielding lid in the first vertical direction and is in close proximity to and laterally aligned with the peripheral edges of the semiconductor device; a core layer that laterally covers the semiconductor device in lateral directions orthogonal to the vertical directions; a first build-up circuitry that covers the semiconductor device and the core layer from the first vertical direction and is electrically connected to the contact pads of the semiconductor device through first conductive vias; and shielding slots that extend through the core layer and laterally cover the semiconductor device and laterally extend beyond peripheral edges of the semiconductor device outward, wherein the shielding slots and the shielding lid are electrically connected to at least one of the contact pads for grounding through the first build-up circuitry.
