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

Claim 14:
15. A semiconductor device comprising:
a substrate;
a doped region in the substrate;
a deep trench capacitor (DTC) having a portion in a trench in the substrate adjacent the doped region, wherein the doped region is spaced apart from the trench;
an interconnect structure over the DTC and the substrate, the interconnect structure comprising:
a first conductive via in physical contact with the doped region;
a first conductive line over the first conductive via, the first conductive line being in electrical contact with the DTC;
a second conductive line over the first conductive line, the second conductive line being in electrical contact with the first conductive via and the first conductive line; and

a contact pad over the interconnect structure, the contact pad being electrically coupled to the doped region through the second conductive line and the first conductive via, wherein the second conductive line is in physical contact with the contact pad.
