Abstract:
An etching method includes a loading step of loading into a chamber a target substrate in which a mask film is laminated on an organic film; a first etching step of etching the organic film below the mask film by plasma of a processing gas in which a flow rate ratio of a second gas containing sulfur to a first gas containing oxygen is set to a first flow rate ratio; and a second etching step of further etching the organic film by plasma of a processing gas in which a flow rate ratio of the second gas to the first gas is set to a second flow rate ratio different from the first flow rate ratio. The first etching step and the second etching step are alternately performed multiple times.

Claim (Index 7):
The etching method of  claim 5 , wherein the third flow rate is 0.
