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 5):
The etching method of  claim 1 , wherein in the first etching step, the first gas is supplied into the chamber at a first flow rate and the second gas is supplied into the chamber at a second flow rate, and\n wherein in the second etching step, the first gas is supplied into the chamber at the first flow rate, and the second gas is supplied into the chamber at a third flow rate smaller than the second flow rate.
