Abstract:
A three-dimensional (3D) integrated circuit (IC) is provided. In some embodiments, a first IC die comprises a first bonding structure and a first interconnect structure over a first semiconductor substrate. A second IC die is disposed over the first IC die and comprises a second bonding structure and a second interconnect structure over a second semiconductor substrate. A seal-ring structure is in the first and second IC dies and extends from the first semiconductor substrate to the second semiconductor substrate. A plurality of through silicon via (TSV) coupling structures is arranged in the peripheral region of the 3D IC along an inner perimeter of the seal-ring structure. The plurality of TSV coupling structures respectively comprises a through silicon via (TSV) disposed in the second semiconductor substrate and electrically coupling to the 3D IC through a stack of TSV wiring layers and inter-wire vias.

Claim (Index 26):
The 3D IC according to  claim 21 , further comprising:\n a plurality of semiconductor openings in the second semiconductor substrate, wherein the plurality of semiconductor openings is directly over the plurality of TSV coupling structures; a plurality of contact openings in the second interconnect structure and through the plurality of semiconductor opening, wherein the plurality of contact openings exposes wiring layers in the second interconnect structure and has a smaller width than the plurality of semiconductor openings; and a plurality of through substrate vias (TSVs) filling the semiconductor and pad openings with an upper surface that is even with an upper surface of the second semiconductor substrate.
