초록

The 200 nm thick-NiCr films grew on $SiO_2$/Si substrates at various deposition temperatures by a dc magnetron co-sputtering technique were characterized for the variation of film texture. The resistivity of the films decreases with increasing deposition temperature and temperature coefficient of electrical resistance (TCR) varies from negative value to a positive one with increasing deposition temperature. The NiCr films deposited at $300^{\circ}C$ exhibit 4 ppm/K being near zero TCR, resulting in TCR suitable for $\pi$-type attenuator applications.
