  • In this study, Pb(Z $r_{0.52}$ $Ti_{0.48}$) $O_{3}$ ceramic thin films were fabricated from an alkoxide-based by Sol-Gel method. Pb(Z $r_{0.52}$ $Ti_{0.48}$) $O_{3}$ stock solution was made and spin-coated on the Pt/ $SiO_{2}$/Si substrate at 4000[rpm] for 30[sec.]. Coated specimens were chied at 400[.deg. C] for 10[min]. The coating process was repeated 6 times and then heat-treated at 500-800[.deg. C] and 1 hour. The final thickness of the thin films were about 4800[.angs.]. The ferroelectric perovskite phases precipitated under the sintering of 700[.deg. C] for 1 hour. Pb(Z $r_{0.52}$ $Ti_{0.48}$) $O_{3}$ thin films sintered at 700[.deg. C] for 1 hour showed good dielectric and ferroelectric properties.
