Abstract:
A method of fabricating a thin film resistor (TFR) and a capacitor on a common integrated circuit (IC) substrate, comprising:depositing a first dielectric layer over existing active device and metal interconnect structures on an IC substrate, depositing a layer of thin film material on said first dielectric layer, depositing a first layer of metal on said thin film material layer, depositing a second dielectric layer over said first layer of metal, depositing a second layer of metal on said second dielectric layer, and patterning and etching said first and second layers of metal, said second dielectric layer, and said thin film material layer to form a TFR having two endcaps and a metal-dielectric-metal capacitor having top and bottom plates on said IC substrate, said first layer of metal providing said TFR's endcaps and said capacitor's bottom plate.
