Abstract:
In a method of an embodiment, a tungsten film is formed on a workpiece. The workpiece includes an underlying film and a mask provided on the underlying film. The tungsten film has a first region extending along the side wall surface of the mask that defines an opening, and a second region extending on the underlying film. Subsequently, the tungsten film is plasma-etched while leaving the first region. In forming the tungsten film, a precursor gas containing tungsten is supplied to the workpiece. Then, plasma of hydrogen gas is generated in order to supply hydrogen active species to the precursor on the workpiece.

Claim (Index 2):
The method of  claim 1 , wherein in the forming the tungsten film, a cycle including the supplying a precursor gas and the generating plasma from hydrogen gas is performed a plurality of times.
