Abstract:
A method for fabricating a thin film resistor, the method comprising:providing a substrate;forming a patterned conductive layer on the substrate, wherein the patterned conductive layer comprises a first opening that exposes the substrate;forming an insulating layer over the substrate so that the first opening is also filled;patterning the insulating layer to form a second opening to expose the first opening and a portion of the patterned conductive layer so that the entire substrate between patterned conductive layer within the first opening is exposed; andforming a thin film resistor over the substrate to entirely cover the second opening patterning the thin film resistor to expose a portion of the insulating layer wherein the thin film resistor entirely covers the opening and a portion of the patterned conductive layer.
