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.

分别采用直流对靶磁控溅射制备低价态氧化钒薄膜再附加热氧化处理的方式，和射频离子束溅射制备高价氧化钒薄膜附加热还原处理的方式获得了具有相变特性的氧化钒薄膜，第一种方式获得相变特性氧化钒薄膜的热处理温度最低为300℃，克服了以往高温条件下热处理不能与MEMS工艺兼容的缺点；相变特性氧化钒薄膜的组分以VO_2为主，含有V2O3和VO_，室温TCR为-2.25%/K；室温电阻温度系数随相变温度的降低逐渐升高；采用第二种方式获得的相变氧化钒薄膜的组分以VO_2为主，含有V2O5和V2O3，室温TCR可达-3.0%/K；分析发现，具有相变特性的氧化钒薄膜中含有V2O5时，室温电阻温度系数明显增大。
