摘要
High-k cobalt-titanium oxide (CoTiO3) film was formed by directly oxidizing sputtered Co/Ti or Ti/Co films. Al/CoTiO3/Si3N4/Si capacitor structures were fabricated and measured. Excellent electrical properties with an effective dielectric constant (i.e., k value) as high as 40 have been achieved for a CoTiO3 gate dielectric with a buffer layer. The metal-oxide thus appears to be a very promising high-k gate dielectric for future ultralarge scale integrated devices.
