One is low valence vanadium oxide thin films were deposited by direct current facing target magnetron sputtering firstly, and then thermal oxidated; the other is high valence vanadium oxide thin films were deposited by ion beam sputtering, then thermal deoxidated. Vanadium oxide thin films with phase transition were obtained at the lower thermal process temperature 300℃, which is compatible with MEMS technologys. The composition of VO_x thin film fabricated by first method includes mainly VO_2, V2O3 and VO_, the TCR is -2.25%/K, the TCR gradually increases with phase transition temperature decreases. The composition of VO_x thin film fabricated by the second method includes mainly VO_2, V2O5 and V2O3 , and the resulting VO_x thin filmTCR is -3.0%/K. The TCR of phase transition vanadium oxide thin films made by second method is higher than that made by first method for the existance of V2O5 in thin films.
