Claim Text:
1. A film-forming method of forming a silicon oxide film, the film-forming method comprising: forming a tungsten film or a tungsten oxide film on a surface of a silicon wafer, the tungsten film or the tungsten oxide film having a first exposed surface and the silicon wafer having a second exposed surface after forming the tungsten film or the tungsten oxide film; heating the first exposed surface and the second exposed surface; forming a first seed layer on the first exposed surface and a second seed layer on the second exposed surface by supplying an aminosilane-based gas simultaneously both on the heated first exposed surface and on the heated second exposed surface, the first seed layer and the second seed layer being a first silicon layer; and forming a second silicon layer on both the first seed layer and the second seed layer by supplying a silicon material gas including silicon on the first seed layer and the second seed layer and then forming a silicon oxide film on both the first seed layer and the second seed layer by supplying a gas including an oxidizing agent on the second silicon layer.
