A microelectronic package includes a substrate (110, 210), an interposer (120, 220) having a first surface (121) and an opposing second surface (122), a microelectronic die (130, 230) attached to the substrate, and a mold compound (140) over the substrate. The interposer is electrically connected to the substrate using a wirebond (150). The first surface of the interposer is physically connected to the substrate with an adhesive (160), and the second surface has an electrically conductive contact (126) formed therein. The mold compound completely encapsulates the wirebond and partially encapsulates the interposer such that the electrically conductive contact in the second surface of the interposer remains uncovered by the mold compound.

摘要:
An offset interposer includes a land side including land-side ball-grid array (BGA) and a package-on-package (POP) side including a POP-side BGA. The land-side BGA includes two adjacent, spaced-apart land-side pads, and the POP-side BGA includes two adjacent, spaced-apart POP-side pads that are coupled to the respective two land-side BGA pads through the offset interposer. The land-side BGA is configured to interface with a first-level interconnect. The POP-side BGA is configured to interface with a POP substrate. Each of the two land-side pads has a different footprint than the respective two POP-side pads.
