Abstract: Disclosed is an etching solution for a silicon substrate. More specifically, an etching solution for a silicon substrate is disclosed in which a concentration of a silane compound (silicon) in the etching solution for the silicon substrate is adjusted to improve an etching selectivity of a silicon nitride film relative to a silicon oxide film during etching of the nitride film.
