Thin films of Pb(Zr0.52Ti0.48)O3 (PZT) were prepared by hybrid processing (sol-gel and excimer laser ablation) on Pt/Ti/SiO2/Si substrates. Crystalline phases and microstructures of the PZT films were investigated by X-ray diffraction analysis and scanning electron microscopy, respectively. Electrical properties of the films were evaluated by measuring their P-E hysteresis loops and dielectric constants. The temperature of postdeposition annealing in hybrid processing was lower than that in the case of direct film deposition by laser ablation on a Pt/Ti/SiO2/Si substrate. The preferred orientation of the films derived by hybrid processing could be controlled using the seeding layer deposited by the sol-gel process. The films fabricated by hybrid processing consisted of the perovskite phase with a (111) preferred orientation and had good ferroelectric properties.
