Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming a first metal oxide film containing at least one or more kinds of elements selected from the group consisting of hafnium, yttrium, lanthanum, aluminium, zirconium, strontium, titanium, barium, tantalum, niobium, on a substrate having a metal thin film formed on the surface, at a first temperature allowing no oxidization of the metal thin film to occur, and allowing the first metal oxide film to be set in an amorphous state, by ALD or CVD method; and forming a second metal oxide film containing at least one or more kinds of elements selected from the group consisting of hafnium, yttrium, lanthanum, aluminium, zirconium, strontium, titanium, barium, tantalum, niobium on the first metal oxide film in the amorphous state formed by film formation at the first temperature, up to a target film thickness for the first and second metal oxide films, at a second temperature exceeding the first temperature, by ALD method or CVD method.
