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 21):
A three-dimensional (3D) integrated circuit (IC), comprising:\n a first IC die with a lower seal-ring structure and a plurality of lower TSV coupling structures arranged in a peripheral region of the first IC die, wherein the first IC die comprises a first interconnect structure over a first semiconductor substrate, a first bonding contact and a first TSV bonding contact over the first interconnect structure, and a first redistribution layer over the first bonding contact and a first TSV redistribution layer over the first TSV bonding contact, and wherein the first interconnect structure, the first bonding contact, and the first redistribution layer define the lower seal-ring structure, and wherein the first interconnect structure, the first TSV bonding contact, and the first TSV redistribution layer define the lower TSV coupling structure; a second IC die with a upper seal-ring structure and a plurality of upper TSV coupling structures corresponding to the lower seal-ring structure and the plurality of lower TSV coupling structures, wherein the second IC die comprises a second interconnect structure over a second semiconductor substrate, a second bonding contact and a second TSV bonding contact over the second interconnect structure, and a second redistribution layer over the second bonding contact and a second TSV redistribution layer over the second TSV bonding contact, and wherein the second interconnect structure, the second bonding contact, and the second redistribution layer define the upper seal-ring structure, and wherein the second interconnect structure, the second TSV bonding contact, and the second TSV redistribution layer define the upper TSV coupling structure; and wherein the second IC die is bonded to the first IC die, and wherein the upper seal-ring structure contacts the lower seal-ring structure at a bonding interface between the first and second redistribution layers to define a seal-ring structure, and the plurality of upper TSV coupling structures contacts the plurality of lower TSV coupling structures at the bonding interface to define a plurality of TSV coupling structures; wherein the lower seal-ring structure comprises a first lower conductive ring and a second lower conductive ring, wherein the first bonding contact and the first redistribution layer are respectively disposed within the first lower conductive rings, and wherein the first bonding contact is absent from the second lower conductive rings.
