Abstract

A method is disclosed of fabricating a MIMCAP (a capacitor (CAP) formed by successive layers of metal, insulator, metal (MIM)) and a thin film resistor at the same level. A method is also disclosed of fabricating a MIMCAP and a thin film resistor at the same level, and a novel integration scheme for BEOL (back-end-of-line processing) thin film resistors which positions them closer to FEOL (front-end-of-line processing) devices.
