  • Patent number: 8796836
    Abstract: A semiconductor device package includes a land grid array package. At least one semiconductor die is mounted to an interposer substrate, with bond pads of the semiconductor die connected to terminal pads on the same side of the interposer substrate as the at least one semiconductor die. Terminal pads of the interposer substrate may be electrically connected to either or both of a peripheral array pattern of lands and to a central, two-dimensional array pattern of pads, both array patterns located on the opposing side of the interposer substrate from the at least one semiconductor die. Additional components, active, passive or both, may be connected to pads of the two-dimensional array to provide a system-in-a-package. Lead fingers of a lead frame may be superimposed on the opposing side of the interposer substrate, bonded directly to the land grid array land and wire bonded to pads as desired for repair or to ease routing problems on the interposer.

  • Patent number: 8772947
    Abstract: Methods for packaging microelectronic devices and microelectronic devices formed using such methods are disclosed herein. One aspect of the invention is directed toward a method for packaging a microelectronic device that includes coupling an active side of a microelectronic die to a surface of a support member. The microelectronic die can have a backside opposite the active side, a peripheral side extending at least part way between the active side and the backside, and at least one through-wafer interconnect. The method can further include applying an encapsulant to cover a portion of the surface of the support member so that a portion of the encapsulant is laterally adjacent to the peripheral side, removing material from a backside of the microelectronic die to expose a portion of at least one through-wafer interconnect, and applying a redistribution structure to the backside of the microelectronic die.
