ABSTRACT:
An improved thin film resistor material is disclosed which comprises a chromium-silicon-carbon material containing from about 25 to 35 wt. % chromium, about 45 to 55 wt. % silicon, and about 20 to 30 wt. % carbon. The resistor material is further characterized by a resistivity of greater than about 800 ohms per square to less than about 1200 ohms per square, a temperature coefficient of resistance of less than 160 ppm per degree Centigrade, and a lifetime stability of less than 0.1% change in resistivity. In the preferred embodiment, the resistor material contains 31 wt. % chromium, 46 wt. % silicon, and 24 wt. % carbon.
