Claim 18:
19. A method of forming a material layer, the method including a deposition cycle comprising:
providing an adsorption inhibitor on a substrate in a reaction chamber;
purging an excess amount of the adsorption inhibitor from the reaction chamber;
providing a metal precursor on the substrate;
purging an excess amount of the metal precursor from the reaction chamber; and
supplying a reactant to form the material layer on the substrate,
wherein the adsorption inhibitor includes nitrogen (N), oxygen (O), phosphorus (P), or sulfur (S), and
the adsorption inhibitor and the metal precursor are supplied into the reaction chamber through a vaporizer, and
wherein the reactant includes one or more selected from a group consisting of nitrogen (N2), ammonia (NH3), hydrazine (N2H4), diazene (N2H2), N2O, NO, NO2, N2 plasma, NH3 plasma, H2 plasma, and NF3.
