N2 - By studying the effects of sputtering current and pressure of gas on the growth rate and quality of Ta2O5 thin films, we have obtained the following optimum technical parameters: Sputtering current-0.6 A; oxygen pressure lower than 3 Pa (for such conditions, the sputtering rate is greater than 64 nm/min.); even and homogeneous film. Using XRD, TEM and SEM measurements, the change of film structure was observed before and after annealing at high temperature. Using XPS, the chemical structure and composition of the Ta2O5 surface was analysed. It is experimentally shown that this film after annealling possesses multicrystalline structure containing Ta2O5 and TaO along (0001) as a textured direction, and excellent electrical, chemical, piezoelectric and sensitive properties.
