Abstract
In a preferred embodiment, a wiring board with embedded device and electromagnetic shielding includes a shielding frame, a semiconductor device, a stiffener, a first build-up circuitry and a second build-up circuitry with a shielding lid. The first and second build-up circuitries cover the semiconductor device, the shielding frame and the stiffener in the opposite vertical directions. The shielding frame and the shielding lid are electrically connected to at least one ground contact pad of the semiconductor device by the first build-up circuitry and can respectively serve as effective horizontal and vertical electromagnetic shields for the semiconductor devices within the aperture of the stiffener.
