Abstract:
An integrated circuit (IC) includes a substrate with a semiconductor surface layer including functional circuitry having a plurality of interconnected transistors including a dielectric layer thereon with a metal stack including a plurality of metal levels over the dielectric layer. A thin film resistor (TFR) layer including at least one metal is within the metal stack. At least one capacitor is within the metal stack including a capacitor dielectric layer over a metal bottom plate formed from one of the metal levels. The capacitor top plate is formed from the TFR layer on the capacitor dielectric layer and there is at least one resistor lateral to the capacitor formed from the same TFR layer.

Claim (Index 1):
A method of fabricating integrated circuits (ICs), comprising:\n depositing a dielectric layer on a semiconductor surface layer on a substrate having a plurality of IC die formed in said semiconductor surface layer with each said IC die including functional circuitry comprising a plurality of interconnected transistors; forming a metal layer over said dielectric layer including for a bottom plate for a capacitor; depositing at least one capacitor dielectric layer on said metal layer; depositing a thin film resistor (TFR) layer comprising at least one metal on said capacitor dielectric layer; forming a first pattern on said TFR layer; etching said TFR layer using said first pattern including defining a top plate comprising said TFR layer on said capacitor dielectric layer and defining said TFR layer lateral to said capacitor form a resistor comprising said TFR layer, and forming a second pattern on said capacitor dielectric layer, etching said capacitor dielectric layer, and then etching said metal layer to define said bottom plate and to complete said capacitor.
