A first gas is introduced for a first time period so components of the first gas adsorb onto the substrate. Subsequently, a second gas is introduced for a second time period so the second gas reacts with the components of the first gas to provide a protective layer on sidewalls of a pattern of the substrate, and the second gas etches a bottom portion of the pattern, a ratio of the first time period to the second time period being a use-ratio. Then, in a second session, the hybrid gas application cycle is repeated with a different use-ratio that corresponds with a vertical dimension of the pattern.

Abstract: A method of etching selectively etches a first region of a substrate with respect to a second region of the substrate formed of a different material from the first region. A deposition film is formed of a chemical species included in plasma generated from a first gas. A gaseous precursor is supplied to the substrate having the deposition film formed thereon to form an adsorption film on the substrate from the precursor. Ions from plasma generated from a second gas are supplied to the substrate having the deposition film and the adsorption film formed thereon so as to cause a reaction between the material of the first region and a chemical species included in the deposition film, so that the first region is etched. The adsorption film reduces the etching rate of the second region during the etching of the first region.
