Patent ID: 11961878
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a substrate;
a deep trench capacitor (DTC) having a portion within a deep trench in the substrate; and
an interconnect structure over the DTC and the substrate, the interconnect structure comprising:
a seal ring structure in electrical contact with the substrate, the seal ring structure surrounding a circuitry;
a first conductive line in electrical contact with the DTC; and
a second conductive line over the first conductive line, wherein the first conductive line electrically couples the second conductive line to the DTC, wherein a portion of one of the first conductive line or a second conductive line is a part of the seal ring structure, wherein the one of the first conductive line or the second conductive line is part of the circuitry.
