Abstract
An EM shielding structure for a semiconductor package is embedded in a through hole of a core layer of the semiconductor package. The EM shielding structure may include multiple vias formed by a copper plating operation. Additionally, a metal way surrounds the EM shielding structures and prevents, along with a dielectric material, unwanted EM radiation (passing through the vias) from emanating throughout the semiconductor package. The EM shielding structure can also take the form of an insert that is adhered to the core layer at a through hole of the core layer.
