Atomic layer deposition apparatus using neutral beam and method of depositing atomic layer using the same
First Claim
1. A method of depositing an atomic layer using a neutral beam, the method comprising:
- 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 the material that cannot be chemisorbed onto the substrate; and
radiating a neutral beam generated by a second reaction gas onto the substrate on which the first reactant adsorption layer is formed, and removing the material not chemisorbed onto the substrate from the first reactant adsorption layer to form a second reactant adsorption layer.

Abstract
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.
