The through silicon vias electrically connect to metal-1 level of the CMOS devices. Copper metal may be plated on a barrier/Cu-seed layer to partially fill the through silicon vias, which saves time and cost. The formation method may involve using dual dielectric layers on the substrate surface as etching mask to eliminate a photolithographical process during the removal of oxide layer at the bottoms of through silicon vias. In some embodiments, the through silicon vias land on polysilicon gate structures to prevent notch formation during etching of the vias.

  • Publication number: 20120049344
    Abstract: A semiconductor die has first and second discrete semiconductor components mounted over a plurality of wettable contact pads formed on a carrier. Conductive pillars are formed over the wettable contact pads. A semiconductor die is mounted to the conductive pillars over the first discrete components. The conductive pillars provide vertical stand-off of the semiconductor die as headroom for the first discrete components. The second discrete components are disposed outside a footprint of the semiconductor die. Conductive TSV can be formed through the semiconductor die. An encapsulant is deposited over the semiconductor die and first and second discrete components. The wettable contact pads reduce die and discrete component shifting during encapsulation. A portion of a back surface of the semiconductor die is removed to reduce package thickness. An interconnect structure is formed over the encapsulant and semiconductor die. Third discrete semiconductor components can be mounted over the semiconductor die.

  • Publication number: 20120049376
    Abstract: An assembly component and a technique for assembling a chip package using the assembly component are described. This chip package includes a set of semiconductor dies that are arranged in a stack in a vertical direction, which are offset from each other in a horizontal direction to define a stepped terraced at one side of the vertical stack. Moreover, the chip package may be assembled using the assembly component. In particular, the assembly component may include a housing having another stepped terrace. This other stepped terrace may include a sequence of steps in the vertical direction, which are offset from each other in the horizontal direction. Furthermore, the housing may be configured to mate with the set of semiconductor dies such that the set of semiconductor dies are arranged in the stack in the vertical direction. For example, the other stepped terrace may approximately be a mirror image of the stepped terrace.
