  • Patent number: 8084300
    Abstract: A method for manufacturing a semiconductor device package to provide RF shielding. The device is mounted on a laminated substrate having conducting pads on its top surface. A molding compound covers the substrate top surface and encapsulates the devices. The substrate is disposed on a tape; the molding compound and the substrate are cut through, forming package units separated by the saw cut width and exposing a portion of a conducting pad. In an embodiment, the tape is stretched to widen the gap between package units. A conductive shield is applied to cover each package unit and to make electrical contact with the exposed conducting pad portion, thereby connecting to a ground trace beneath the device and providing RF shielding for the device. A single-unit molding process may be used, in which the conducting pad is exposed during and after molding.

  • Patent number: 7439097
    Abstract: The invention provides a taped lead frame for use in manufacturing electronic packages. The taped lead frame is composed of a tape and a lead frame formed from a plurality of individual metal features attached to the tape and arranged in a footprint pattern. The method of making the invention enables the thickness of conventional frames to shrink significantly to result in thinner packages for improved heat dissipation and shorter geometries for improved electrical performance. A plurality of such lead frames are arranged in an array on a sheet of tape and each lead frame is separated from surrounding lead frames by street regions on the tape such that no metal feature extends into a street region. Integrated circuit chips are attached and electrically connected to the lead frames and an encapsulant is applied, cured and dried over the lead frames and the street regions.
