Semiconductor packaging for a memory device and a fabricating method thereof

摘要

A semiconductor device includes a substrate, a semiconductor chip, a first molding member and a metal layer. The substrate includes a first ground pad formed therein, the first ground pad having a first exposed surface exposed at a first surface of the substrate. The semiconductor chip is formed on the first surface of the substrate. The first molding member is formed on the first surface of the substrate and covers the semiconductor chip while not covering the first exposed surface. The metal layer covers the first molding member and extends to lateral surfaces of the substrate while contacting the first exposed surface.
