Patent ID: 8735304

Claim:
A method of forming a dielectric film which includes a zirconium oxide film, the method comprising: forming a zirconium oxide film on a substrate to be processed by alternately supplying a zirconium material and an oxidant into a processing vessel several times, the zirconium material including cyclopentadienyl.tris(dimethylamino)zirconium or methylcyclopentadienyl.tris(dimethylamino)zirconium, wherein a side opposite to a cyclopentadienyl ring in the zirconium material becomes an adsorption site to the substrate; and forming a titanium oxide film on the zirconium oxide film by alternately supplying a titanium material and the oxidant into the processing vessel several times, the titanium material including methylcyclopentadienyl.tris(dimethylamino)titanium, wherein a side opposite to a cyclopentadienyl ring in the titanium material becomes an adsorption site to the zirconium oxide film.
