Abstract:
The present disclosure relates to an etching method including: a first step of forming an etching assistance layer on a surface of at least one of a plurality of silicon-containing regions by plasma of a processing gas generated in a processing container; and a second step of imparting energy to the etching assistance layer. The energy is equal to or greater than energy at which the etching assistance layer is removed, and smaller than energy at which a region located immediately below the etching assistance layer is sputtered, and a sequence including the first step and the second step is executed repeatedly.

Claim (Index 5):
The method of  claim 7 , wherein the carbon-containing gas is a hydrofluorocarbon gas or a fluorocarbon gas,\n the oxygen-containing gas is O 2 , CO, COS, or CO 2 , the nitrogen-containing gas is N 2 , NH 3 , or NF 3 , the halogen-containing gas is Cl 2 , HBr, NF 3 , C x H y F z , or C x F y  (x, y, and z are natural numbers), and the hydrogen-containing gas is H 2 .
