ABSTRACT: The ZrO2 thin films deposited on Si (100) were successfully synthesized by solgel process and deposited by using spin-coating technique.The structural properties of ZrO2 thin films were investigated by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and electrical properties were studied by conventional techniques like Capacitance-Voltage (C-V) measurement and Current–Voltage (I–V) measurement. The XRD of ZrO2 films shows the films crystallized and exists in two phases at 700℃ calcinations temperature. The C–V characteristics of all the dielectric films that involved distinct inversion, depletion, and accumulation were clearly revealed in MIS structure. I-V characteristics of ZrO2 thin films on Si shows decreased saturation current on calcinations temperatures. The XPS measurement reveals that a zirconium silicate interfacial layer has formed in the ZrO2/Si Systems.
