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

Claim 3:
4. An integrated chip (IC), comprising:
a substrate;
a resistor overlying the substrate, wherein the resistor comprises:
a first metal nitride structure;
a second metal nitride structure spaced from the first metal nitride structure; and
a metal structure disposed between the first metal nitride structure and the second metal nitride structure; and

a first dielectric structure disposed over the substrate and the resistor,
wherein the first metal nitride structure is tantalum nitride (TaN);
the metal structure is tantalum (Ta);

the second metal nitride structure is TaN; and
a pair of conductive structures extending through the first dielectric structure and electrically coupled to the resistor, wherein a first conductive structure of the pair of conductive structures is directly contacting the second metal nitride structure.
