Polycrystalline titanium oxide films are fabricated on silicon by thermally oxidizing titanium.The current-voltage and capacitance-voltage characteristics of the Ag/TiOx/Si/Ag capacitors are measured.The thickness of the titanium oxide films arranges from 150nm to 250nm,and their dielectric constants are within 40~87.As the oxidation time is shortened,the fixed charges of the titanium oxide films become less and the leakage current characteristics become better.
