  • Publication number: 20130214410
    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.

  • Patent number: 8508029
    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.
