Processing and Performance of Tantalum Nitride Thin Film

Vacuum annealing has bean used to routinely manufacture tantalum nitride resistor networks with temperature coefficients in the range of ±50 ppm/°oC. The as-sputtered temperature coefficient of resistance (TCR) of tantalum nitride films with nitrogen content set for optimum stability is approximately --130 ppm. Although near zero TCR's can be obtained by reducing the nitrogen
