Patent ID: 8404603

Claim:
A method of manufacturing a semiconductor device, the method comprising: alternately repeating: a process of supplying and exhausting an aluminum precursor into and from a processing chamber where the substrate is accommodated, and a process of supplying and exhausting one of an oxidizing precursor and a nitriding precursor into and from the processing chamber to form an aluminum-containing insulation film on an electrode film formed on a surface of a substrate; alternately repeating: a process of supplying and exhausting a precursor into and from the processing chamber; and a process of supplying and exhausting an oxidizing precursor into and from the processing chamber to forming a high permittivity insulation film different from the aluminum-containing insulation film on the aluminum-containing insulation film; and thermally diffusing aluminum in the aluminum-containing insulation film into the high permittivity insulation film by subjecting the substrate having the high permittivity insulation film thereon to a heat treatment process so as to dope the high permittivity insulation film.
