Tungsten defluorination by high pressure treatment
An annealing system is provided that includes a chamber body that defines a chamber, a support to hold a workpiece and a robot to insert the workpiece into the chamber. The annealing system also includes a first gas supply to provide a hydrogen gas, a pressure source coupled to the chamber to raise a pressure in the chamber to at least 5 atmospheres, and a controller configured to cause the robot to transport a workpiece having a metal film thereon into the chamber, where the metal film contains fluorine on a surface or embedded within the metal film, to cause the first gas supply to supply the hydrogen gas to the chamber and form atomic hydrogen therein, and to cause the pressure source to raise a pressure in the chamber to at least 5 atmospheres while the workpiece is held on the support in the chamber.

METHOD AND DEVICE FOR FORMING TUNGSTEN FILM, AND DEVICE FOR FORMING INTERMEDIATE FILM BEFORE FORMING TUNGSTEN FILM
The formation of a tungsten film is promoted when forming the tungsten film using tungsten chloride on an upper layer side of a titanium silicon nitride film. A titanium silicon nitride film is formed on one surface side of a semiconductor wafer as a substrate, and an intermediate film for promoting the formation of the tungsten film made of the tungsten chloride is formed on the upper layer side of the titanium silicon nitride film by using a gas for forming the intermediate film. The tungsten film is formed on an upper layer side of the intermediate film by using a gas of the tungsten chloride.
