Claim:
1. A method of depositing a layer, the method comprising: spraying a source gas and a reactant gas onto a substrate disposed on a susceptor unit using at least one source gas spray nozzle and at least one reactant gas nozzle to form a first source gas region and a first reactant gas region on the substrate, respectively, the at least one source gas spray nozzle and the at least one reactant gas spray nozzle being alternately arranged in a gas spray unit; moving the susceptor unit by a distance corresponding to a width of the at least one source gas spray nozzle or a width of the at least one reactant gas spray nozzle in a first direction so that the at least one reactant gas spray nozzle is disposed over the first source gas region and the at least one source gas spray nozzle is disposed over the first reactant gas region; and spraying the source gas and the reactant gas onto the first reactant gas region and the first source gas region using the at least one source gas spray nozzle and the at least one reactant gas nozzle, respectively, to form a first monolayer.
