Patent ID: 10096555

Abstract:
Consistent with an example embodiment, a semiconductor device comprises a device die having bond pads providing connection to device die circuitry and a QFN half-etched lead frame with a package boundary; the QFN half-etched lead frame has a top-side surface and an under-side surface. The QFN half-etched lead frame includes a sub-structure of I/O terminals and a die attach area, the die attach area facilitating device die attachment thereon and the terminal I/O terminals providing connection to the device die bond pads and additional terminals located about the corners of the sub-structure. An envelope of molding compound encapsulates the device die mounted on the top-side surface of the QFN half-etched lead frame. A RF (radio-frequency) shield layer is on the envelope of the molding compound, the RF shield electrically connected to the additional terminals via conductive connections defined in corresponding locations on the envelope of the molding compound.
