VO_(x) thin films was prepared on Pt/Ti/SiO₂/Si substrate at room temperature by rf magnetron sputtering method. The deposition rate of VO_(x) thin films was investigated as a function of dc power and working gas. As dc power increased, the deposition rate increased. However, as the O₂ concentration in a O₂/Ar mixture increased, the deposition rate decreased. The phase change of deposited VOX thin films was investigated by x-ray diffraction. The plane and cross-sectional views of VO_(x) thin films before and after annealing were observed by field emission scanning electron microscopy. Metal insulator transition property of VO₂ thin films was measured using current-voltage measurement.
