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

Claim 7:
8. A semiconductor structure comprising:
a first substrate and a second substrate;
a first trench capacitor and a second trench capacitor extending respectively into a front side of the first substrate and a front side of the second substrate, wherein the front sides of the first and second substrates face each other;
a plurality of wires and a plurality of vias stacked between and electrically coupled to the first and second trench capacitors; and
a through substrate via (TSV) extending through the first substrate from a back side of the first substrate opposite the front side of the first substrate;
wherein the plurality of wires and the plurality of vias define a first conductive path extending from the TSV to the first trench capacitor and further define a second conductive path extending from the TSV to the second trench capacitor, and wherein the first and second conductive paths are different.
