Abstract: PZT thin films were fabricated on (111)Pt/Ti/SiO2/Si by RF magnetron sputtering with a ceramic target(PZT53/47). The as-deposited
thin films were annealed with a rapid thermal annealing process. XRD was used to determine the structure of the thin films. This paper focused on the
research about the influence of sputtering gas and substrate temperature on the structure of the thin films. It was found that the process of phase
transformation of PZT thin films changed with the ratio of Ar to O2 and substrate temperatures. The ferroelectric property of PZT thin films
was measured by RT66A standardized ferroelectric test system. When 5V voltage was applied, the film showed a remnant polarization of 14.6μC/cm2, and coercive
field of 82.9kV/cm.
