TaN film resistors were fabricated on the Al2O3 substrate by reactive sputtering. For TaN film resistor samples, the changes of the surface temperatures with different loading power densities were investigated. The failure of TaN film resistors under high temperature was analyzed, which can be ascribed to the oxidation of TaN. The TaN film resistors with the thickness of 0.1μm on 0.125 mm Al2O3 substrate can tolerate the power density of 4 W/mm2 or the pulse power density of 9.4 W/mm2 with the duration of 1 min at 70℃under the IC test specification.
