A method for depositing ferroelectric thin films of Pb(Zr0.47 Ti0.53)O3 on platinized silicon by Sol-Gel technique is described. The ferroelectric thin film was investigated by XPS, SEM and XRD etc. and its hysteresis loop and C-V curve were measured by RT66A Standard Ferroelectric Meter. The effects of various processing parameters on the performance of the PZT capacitors are presented.
