Abstract

See full text

An integrated circuit contains a thin film resistor in which a body of the thin film resistor is disposed over a lower dielectric layer in a system of interconnects in the integrated circuit. Heads of the thin film resistor are disposed over electrodes which are interconnect elements in the lower dielectric layer, which provide electrical connections to a bottom surface of the thin film resistor. Top surfaces of the electrodes are substantially coplanar with a top surface of the lower dielectric layer. A top surface of the thin film resistor is free of electrical connections. An upper dielectric layer is disposed over the thin film resistor.
