    Abstract: High resistivity, low temperature coefficient of resistance films are formed by evaporating a molybdenum or tungsten source in a low-pressure atmosphere, e.g. 5 X 10 4 torr, of a nitrogen bearing gas, a carbon bearing gas or an inert gas and depositing a resistor film atop a preferably unheated dielectric substrate.

    Abstract: Low temperature coefficient of resistance, high resistivity films of a refractory metal/refractory metal nitride are formed by sputtering a tungsten or molybdenum cathode in a chamber containing a mixture of an inert gas and nitrogen wherein nitrogen forms between 0.3 and 3.0 percent of the sputtering chamber pressure. The deposited films characteristically are a mixture of the sputtered metal and at least 5 percent by volume of the metal nitride with films having especially superior electrical characteristics containing the metal nitride in concentrations between approximately 40 and 60 percent by volume of the resistor film.
