    Abstract: Methods, systems, and apparatuses for integrated circuit packages are provided. An integrated circuit package, such as a quad flat no-lead (QFN) package, includes a plurality of peripherally positioned leads, a heat spreader, an integrated circuit die, and an encapsulating material. The peripherally positioned leads are attached to a first surface of the heat spreader, and the die is attached to the first surface of the heat spreader within a ring formed by the leads. The encapsulating material encapsulates the die on the heat spreader, encapsulates bond wires, and fills a space between the leads. A second surface of the heat spreader is exposed from the package. End portions of the leads have surfaces that are flush with a surface of the package opposite the second surface of the heat spreader, and that are used as lands for the package.

  • Patent number: 8670638
    Abstract: Methods and apparatus are disclosed for wirelessly communicating among integrated circuits and/or functional modules within the integrated circuits. A semiconductor device fabrication operation uses a predetermined sequence of photographic and/or chemical processing steps to form one or more functional modules onto a semiconductor substrate. The functional modules are coupled to an integrated waveguide that is formed onto the semiconductor substrate and/or attached thereto to form an integrated circuit. The functional modules communicate with each other as well as to other integrated circuits using a multiple access transmission scheme via the integrated waveguide. One or more integrated circuits may be coupled to an integrated circuit carrier to form Multichip Module. The Multichip Module may be coupled to a semiconductor package to form a packaged integrated circuit.

  • Publication number: 20140061893
    Abstract: Flip chip packages are described that include two or more thermal interface materials (TIMs). A die is mounted to a substrate by solder bumps. A first TIM is applied to the die, and has a first thermal resistance. A second TIM is applied to the die and/or the substrate, and has a second thermal resistance that is greater than the first thermal resistance. An open end of a heat spreader lid is mounted to the substrate such that the die is positioned in an enclosure formed by the heat spreader lid and substrate. The first TIM and the second TIM are each in contact with an inner surface of the heat spreader lid. A ring-shaped stiffener may surround the die and be connected between the substrate and heat spreader lid by the second TIM.

  • Patent number: 8664772
    Abstract: An interface substrate is disclosed which includes an interposer having through-semiconductor vias. An upper and a lower organic substrate are further built around the interposer. The disclosed interface substrate enables the continued use of low cost and widely deployed organic substrates for semiconductor packages while providing several advantages. The separation of the organic substrate into upper and lower substrates enables the cost effective matching of fabrication equipment. By providing an opening in one of the organic substrates, one or more semiconductor dies may be attached to exposed interconnect pads coupled to through-semiconductor vias of the interposer, enabling the use of flip chips with high-density microbump arrays and the accommodation of dies with varied bump pitches. By providing the opening specifically in the upper organic substrate, a package-on-package structure with optimized height may also be provided.

  • Publication number: 20130311127
    Abstract: Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.
