Abstract:
A method for forming a silicon oxide film on a tungsten film includes performing a first process of arranging an object to be processed in a processing container kept under a reduced pressure, the object including a tungsten film and a natural oxide film being formed on a surface of the tungsten film, performing a second process of forming a silicon seed layer by adsorbing a silicon-containing gas to the tungsten film, subsequently performing a third process of annealing the object and forming the silicon oxide film by a reaction of the natural oxide film and the silicon seed layer and subsequently performing a fourth process of forming an ALD silicon oxide film by ALD using a silicon-containing gas and an oxygen active species.

Claim (Index 16):
The apparatus of  claim 15 , wherein the control part controls the at least one of the gas supply part, the heating mechanism and the exhaust mechanism to form the first ALD silicon oxide film by using diisopropylaminosilane gas as the aminosilane-based gas and to form the second ALD silicon oxide film by using a hexachlorodisilane gas as the silane-based gas containing chlorine.
