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 11):
The method of  claim 1 , wherein the object is a semiconductor wafer forming a 3D-NAND type nonvolatile semiconductor device.
