  • Integrated circuit with thin film resistors and a method for co-patterning thin film resistors with different compositions
    Patent number: 5976944
    Abstract: FIG. 5b shows a first thin film resistor 14 formed by direct etching or lift off on a first dielectric layer 12 that covers an integrated circuit (not shown) in a silicon substrate 10. A patterned layer of photoresist covers a portion of the second thin film resistor material 30. The second thin film resistor material 30 is different from the first thin film resistor material 14. The exposed portion of the second thin film resistor material 30 is removed to leave first and second thin film resistors on the first dielectric layer 12.
