Abstract:
A technique relates to forming resistor fins on a substrate. A shallow trench isolation material is formed on dummy fins and the substrate, and the dummy fins are formed on the substrate. Predefined ones of the dummy fins are removed, thereby forming voids in the shallow trench isolation material corresponding to previous locations of the predefined ones of the dummy fins. A first material is deposited into the voids. The height of the first material is reduced, thereby forming trenches in the shallow trench isolation material. A second material is deposited into the trenches to be on top of the first material, thereby forming the resistor fins of a resistor device. A metal contact layer is formed so as to contact a top surface of the first material at predefined locations.
