Abstract
Disclosed is a carbon thin-film device and method for manufacturing the same. The method includes forming a functional group on a surface of a substrate and functionalizing the substrate, and depositing a carbon thin film through ALD on the substrate in which the functional group is formed.
Claims6
A method of manufacturing a carbon thin-film device, the method comprising:
- forming a functional group on a surface of a substrate which does not have a metal layer on the surface to functionalize the surface of the substrate, the functional group comprising a hydroxyl group;
- pre-supplying carbon tetrabromide (CBr4) to the substrate, on which the hydroxyl group is formed;
- and
- depositing a carbon thin film through atomic layer deposition on the substrate, after the carbon tetrabromide is pre-supplied to the substrate,
- wherein the functionalizing of the substrate includes forming an adsorption layer, which includes the functional group, on the substrate, the adsorption layer being formed of a single atomic layer or a single molecular layer,
- wherein atoms of the adsorption layer are covalent-bonded with atoms of the substrate, and carbon atoms of a basal layer of the carbon thin film are covalent-bonded with the atoms of the adsorption layer,
- wherein the depositing of the carbon thin film on the substrate includes repeating unit cycles a number of times,
- wherein the unit cycle includes
- supplying halocarbon as carbon precursors to the substrate after the carbon tetrabromide is pre-supplied on the substrate;
- supplying a purge gas to the substrate to purge the substrate;
- supplying a reaction gas to the substrate;
- and
- supplying the purge gas to the substrate to purge the substrate.
