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 12):
An apparatus for forming a silicon oxide film on a tungsten film, comprising:\n a processing container configured to accommodate an object to be processed, the object including a tungsten film and a natural oxide film being formed on a surface of the tungsten film; a gas supply part configured to supply a predetermined gas into the processing container; a heating mechanism configured to heat an inside of the processing container; an exhaust mechanism configured to exhaust the inside of the processing container such that the processing container is in a depressurized state; and a control part configured to control the gas supply part, the heating mechanism, and the exhaust mechanism, wherein the control part controls at least one of the gas supply part, the heating mechanism, and the exhaust mechanism, to keep the inside of the processing container under a reduced pressure in a state in which the object is arranged inside the processing container, to form a silicon seed layer by supplying a silicon-containing gas into the processing container and absorbing the silicon-containing gas to the tungsten film, to subsequently anneal the object and form a silicon oxide film by a reaction of the natural oxide film and the silicon seed layer, and to supply a silicon-containing gas and oxygen active species alternately and form an ALD silicon oxide film by ALD.
