Patent ID: 11862612
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. An integrated circuit (IC) comprising:
a first IC die comprising a first substrate, a first trench capacitor under the first substrate, and a first interconnect structure under the first trench capacitor;
a second IC die under and bonded to the first IC die, wherein the second IC die comprises a second substrate, a second trench capacitor over the second substrate, and a second interconnect structure over the second trench capacitor; and
a through substrate via (TSV) extending through the first IC die from a top of the first substrate to the second IC die, wherein the TSV is electrically coupled to the first and second trench capacitors by the first and second interconnect structures;
wherein the TSV extends through and laterally contacts a first TSV wire in the first interconnect structure, and further extends to and terminates at a second TSV wire spaced from the first TSV wire and in the second interconnect structure.
