摘要
We have developed a novel material of silicon titanium oxide with high dielectric constant and low leakage current. The silicon titanium oxide films were prepared by plasma-enhanced chemical vapor deposition (plasma CVD) with the gas mixture of TiCl4-SiH4-N2O. It was found that these films have intermediate properties of silicon dioxide and titanium dioxide by varying the ratio of SiH4/(SiH4 + TiCl4). The properties of silicon titanium oxide nearly corresponded to those of Ta2O5 when the gas mixture ratio was 0.075, with a dielectric constant of 18 and a leakage current density of 2.5 x 10(-8) A/cm2 at 1 MV/cm.
