Abstract: The resistance value of a refractory metal carbide film resistor is adjusted and stabilized at any desired resistance value up to approximately 100 times the resistance value of the originally deposited film by heat treating the metal carbide film in an oxidizing atmosphere at temperatures above the anticipated operating range of the resistor. The heat treatment increases the resistance of the applied film by converting a layer of the exposed film to a non-conductive oxide.
