BOÎTIER SEMICONDUCTEUR DOTÉ D'UN BLINDAGE COMPARTIMENTAL DANS LE BOÎTIER ET D'UNE PROTECTION ACTIVE DE COMPATIBILITÉ ÉLECTROMAGNÉTIQUE

摘要

A semiconductor package includes a substrate having a semiconductor chip disposed on a top surface of the substrate, a ground ring surrounding the semiconductor chip on the top surface of the substrate, a metal-post reinforced glue wall disposed on the ground ring to surround the semiconductor chip, and a molding compound disposed only inside the metal-post reinforced glue wall and covering the semiconductor chip. The metal-post reinforced glue wall comprises a magnetic or magnetizable filler so as to form an active electro-magnetic compatibility (EMC) shielding.
