Semiconductor packages having EMI shielding layers, methods of fabricating the same, electronic systems including the same, and memory cards including the same

摘要

Semiconductor packages are provided. In some embodiments, the semiconductor package includes a substrate, a first ground line including a first internal ground line disposed along edges of the substrate and a plurality of first extended ground lines between the first internal ground line and sidewalls of the substrate, a chip on the substrate, a molding member disposed on the substrate to cover the chip, and an electromagnetic interference (EMI) shielding layer covering the molding member, the EMI shielding layer extending along the sidewalls of the substrate and contacting the end portions of the plurality of first extended ground lines. The plurality of first extended ground lines include end portions that are exposed at the sidewalls of the substrate.
