Abstract: PURPOSE: A method for preparing a nano-film by selective area coating is provided, to prepare a metal/oxide multilayered bottom-up nano-film without the deterioration of characteristics. CONSTITUTION: The method comprises the steps of preparing a charged particle of an atom or molecule unit by using a material forming a thin film; forming a bias locally on the electrode where nano-sized pattern is formed; and coating the charged particle on the nano-pattern selectively to form a nano-film. Preferably the material forming a thin film is at least one selected from the group consisting of metals, oxides and nitrides; and a substrate (electrode) is locally biased by the self-bias due to the difference of area or the difference of charge density.
