Pb 0.3 Sr 0.7 TiO 3 (PST) and Bi 1.5 Zn 0.5 Nb 0.5 Ti 1.5 O 7 (BZNT) thin films were deposited on Pt/Ti/SiO 2 /Si substrates by Sol-gel and radio frequency (rf) magnetron sputtering, respectively. The dielectric and tunable properties of thin films were investigated as a function of heat treatment processes. It’s found that the heat treatment process at the appropriate temperature and time can be used to obtain a good thin film. The film has the best comprehensive dielectric properties by annealing at 650°C for 45min, the figure of merit (FOM) is 20.1.
