  • Publication number: 20120319282
    Abstract: Methods and apparatus for forming a semiconductor device are provided which may include any number of features. One feature is a method of forming an interconnect structure that results in the interconnect structure having a top surface and portions of the side walls of the interconnect structure covered in a dissimilar material. In some embodiments, the dissimilar material can be a conductive material or a nano-alloy. The interconnect structure can be formed by removing a portion of the interconnect structure, and covering the interconnect structure with the dissimilar material. The interconnect structure can comprise a damascene structure, such as a single or dual damascene structure, or alternatively, can comprise a silicon-through via (TSV) structure.

  • Publication number: 20120273933
    Abstract: A microelectronic assembly can include first, second and third stacked substantially planar elements, e.g., of dielectric or semiconductor material, and which may have a CTE of less than 10 ppm/° C. The assembly may be a microelectronic package and may incorporate active semiconductor devices in one, two or more of the first, second or third elements to function cooperatively as a system-in-a-package. In one example, an electrically conductive element having a minimum thickness less than 10 microns, may be formed by plating, and may electrically connect two or more of the first, second or third elements. The conductive element may entirely underlie a surface of another one of the substantially planar elements.
