Abstract:
1. A method for manufacturing an integrated circuit, said method comprising the steps of: forming a thin film resistor on an integrated circuit substrate; forming a resistor protect layer over said thin film resistor; forming a layer of first dielectric material over said resistor protect layer; depositing a resist mask over portions of said layer of first dielectric material; etching said first dielectric material to leave a first portion of said first dielectric material over a first end of said thin film resistor and a second portion of said first dielectric material over a second end of said thin film resistor; etching a first via through said first portion of said first dielectric material down to said resistor protect layer that is located over said first end of said thin film resistor; and etching a second via through said second portion of said first dielectric material down to said resistor protect layer that is located over said second end of said thin film resistor.
