| description | There is provided a stress reducing method comprising: preparing a film forming apparatus configured to form a tungsten film on a substrate in a chamber by supplying a tungsten raw material gas and a reducing gas into the chamber; and making at least a part of a tungsten film deposited on an in-chamber component into a chlorine-containing tungsten film whose film stress is reduced by adjusting a chlorine concentration, when performing precoating in the chamber and/or when forming the tungsten film on the substrate, using the tungsten raw material gas and the reducing gas. |
