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

Claim 0:
1. A semiconductor structure comprising:
a first substrate and a second substrate underlying the first substrate;
a first trench capacitor and a second trench capacitor between the first and second substrates and extending respectively into the first and second substrates;
a plurality of wires and a plurality of vias stacked between and electrically coupled to the first and second trench capacitors;
a through substrate via (TSV) extending through the first substrate from a top of the first substrate to a bottom of the first substrate, wherein the wires and the vias electrically couple the TSV to the first and second trench capacitors; and
a dielectric layer between the first trench capacitor and the first substrate, wherein the first trench capacitor extends completely through the dielectric layer into the first substrate.
