Abstract:
Disclosed is a method for etching an etching target layer which contains silicon and is provided with a metal-containing mask thereon. The method includes: generating plasma of a first processing gas containing a fluorocarbon gas in a processing container that accommodates the etching target layer and the mask to form a fluorocarbon-containing deposit on the mask and the etching target layer; and generating plasma of a second processing gas containing an inert gas in the processing container to etch the etching target layer by radicals of the fluorocarbon contained in the deposit. A plurality of sequences, each including the generating the plasma of the first processing gas and the generating the plasma of the second processing gas, are performed.

Claim (Index 13):
The method of  claim 1 , wherein a deposition pressure in the forming the fluorocarbon-containing deposit and an etching pressure in the etching the silicon-containing layer are the same.
