Zusammenfassung:A method for atomic layer etching may include a step of providing a substrate on which a material to be etched is formed, a modifying step of controlling the substrate at a first temperature and modifying a surface layer of the material to be removed by supplying a modifying gas to the substrate, and an etching step of controlling the substrate at a second temperature different from the first temperature and removing the modified surface layer by supplying an etching gas to the substrate.
