Abstract:
Integrated circuits with a resistance element and gate-last techniques for forming the integrated circuits are provided. An exemplary technique includes providing a semiconductor substrate that includes a shallow trench isolation (STI) structure disposed therein. A dummy gate electrode structure is patterned overlying semiconductor material of the semiconductor substrate, and a resistor structure is patterned overlying the STI structure. The dummy gate electrode structure and the resistor structure include a dummy layer overlying a metal capping layer. A gate dielectric layer underlies the metal capping layer. An interlayer dielectric layer is formed overlying the semiconductor substrate and the STI structure. End terminal recesses for the resistance element are concurrently patterned through the dummy layer of the resistor structure along with removing the dummy layer of the dummy gate electrode structure to form a gate electrode recess. Metal gate material is deposited in the end terminal recesses and a gate electrode recess.
