Abstract

In a method of forming a thin film and methods of manufacturing a gate structure and a capacitor, a hafnium precursor including one alkoxy group and three amino groups, and an oxidizing agent are provided on a substrate. The hafnium precursor is reacted with the oxidizing agent to form the thin film including hafnium oxide on the substrate. The hafnium precursor may be employed for forming a gate insulation layer of a transistor or a dielectric layer of a capacitor.
