Abstract:
A method of etching a multilayered film including multiple silicon oxide films and multiple silicon nitride films is provided. A mask containing carbon is provided on the multilayered film. The method includes performing a first plasma processing and performing a second plasma processing. In the performing of the first plasma processing and in the performing of the second plasma processing, plasma of a processing gas is generated within a chamber in a state that a temperature of an electrostatic chuck, on which a processing target object is placed, is set to be equal to or less than −15° C. The processing gas contains a hydrogen atom, a fluorine atom, a carbon atom and an oxygen atom, and also contains a sulfur-containing gas. A pressure of the chamber in the performing of the first plasma processing is set to be lower than that in the performing of the second plasma processing.

Claim (Index 5):
The method of  claim 1 ,\n wherein the processing gas contains a hydrogen bromide.
