  • Patent number: 8269326
    Abstract: An interposer includes a substrate, a conductive structure configured to contact the back side of a semiconductor device and contact pads. The interposer may include first and second sets of contact pads carried by the substrate. The interposer may also include conductive traces carried by the substrate to electrically connect corresponding contact pads of the first and second sets. The receptacles, which may be formed in a surface of the substrate and expose contacts of the second set, may be configured to at least partially receive conductive structures that are secured to the contact pads of the second set. Thus, the interposer may be useful in providing semiconductor device assemblies and packages of reduced height or profile. Such assemblies and packages are also described, as are multi-chip modules including such assemblies or packages.
