Abstract:
An etching method can protect a mask with a material having higher etching resistance to a silicon-containing film. The etching method is performed in a state that a processing target object is placed within a chamber main body. The etching method includes forming a tungsten film on the processing target object and etching the silicon-containing film of the processing target object. The forming of the tungsten film includes supplying a gaseous tungsten-containing precursor onto the processing target object; and generating plasma of a hydrogen gas to supply active species of hydrogen to the precursor on the processing target object. In the etching of the silicon-containing film, plasma of a processing gas containing fluorine, hydrogen and carbon is generated within the chamber main body.

Claim (Index 10):
The workpiece processing method of  claim 8 , further comprising etching the silicon-containing film after the forming of the tungsten-containing film.
