US Patent 7576415 EMI shielded semiconductor package

An EMI shielded semiconductor package is provided. The package includes a substrate and a chip disposed on the substrate. The chip is electrically connected to the substrate by a plurality of bonding wires. At least one shielding conductive block is formed on the substrate and electrically connected to the ground trace of the substrate. A sealant is formed on the substrate and covers the chip, bonding wires and the shielding conductive block. The sealant has a side surface to expose a surface of the shielding conductive block. A layer of conductive film is formed on the outer surface of the sealant and covers the exposed surface of the shielding conductive block thereby shielding the chip from electromagnetic interference.
