The PZT thin films were deposited on Pt/Ti/SiO2/Si substrate by R.F. Magnetron Sputtering with Pb1.1Zr0.53Ti0.47O3 target. When interlayers(PbO, TiO2, PbO/TiO2) were inserted between PZT and Pt, the crystallization of the PZT thin films was considerably improved and the processing temperature was lowered. Compared to the pure PZT thin films, dielectric constant, dielectric loss, and polarization properties of PZT thin films with interlayers were considerably improved. From XPS depth profile analysis, it was confirmed that PZT thin films and interlayers existed independently. In particular, PZT thin films deposited on interlayer(PbO/TiO2) showed the best dielectric property (εr=414.94, tanδ=0.0241, Pr=22 μC/㎠).
