Claim Text:
1. A method of forming a thin film on a substrate using a vapor deposition apparatus, the method comprising: performing a deposition process on the substrate, the deposition process including injecting at least one raw material gas towards the substrate while moving the substrate on a stage relative to a supply unit that injects the at least one raw material gas; and blocking a flow of the raw material gas using a gas flow generated by a blocking gas flow generation unit that is disposed corresponding to the supply unit such that the blocking gas flow generation unit injects a blocking gas in a direction counter to an injection direction of the raw material gas from the supply unit such that the flow of the raw material gas in the injection direction of the raw material gas is blocked to prevent the raw material gas from contaminating a bottom surface of the vapor deposition apparatus opposite the supply unit in the injection direction of the raw material gas from the supply unit.
