Disclosed are an atomic layer deposition apparatus using a neutral beam and a method of depositing an atomic layer using the apparatus, capable of converting an ion beam into a neutral beam and radiating it onto a substrate to be treated. The method uses an apparatus for supplying a first reaction gas containing a material that cannot be chemisorbed onto a substrate to be treated into a reaction chamber in which the substrate is loaded, and forming a first reactant adsorption layer containing a material that cannot be chemisorbed onto the substrate; and radiating a neutral beam generated by the second reaction gas onto the substrate on which the first reactant adsorption layer is formed, and removing a material not chemisorbed onto the substrate from the first reactant adsorption layer to form a second reactant adsorption layer. It is possible to perform a process without damage due to charging with the apparatus for depositing an atomic layer using a neutral beam and the method of depositing an atomic layer using the apparatus.
