Claim Text:
1. In a thin film vapor deposition method using a thin film vapor deposition apparatus including a substrate support unit which is installed in a reactor, and is provided with a plurality of substrate seat portions on which a plurality of substrates are put, and a gas injection unit which is installed above the substrate support unit, and has a source gas supplier for feeding a source gas onto the substrate support unit, a reaction gas supplier for feeding a reaction gas which is reacted with the source gas onto the substrate support unit, and a mixed gas supplier for feeding a mixed gas of the reaction gas and an inert gas onto the substrate support unit, the source gas supplier, the reaction gas supplier, and the mixed gas supplier being radially disposed, and the mixed gas supplier being disposed between the source gas supplier and the reaction gas supplier, a method of vapor depositing a thin film using the thin film vapor deposition apparatus, in which the substrate support unit and the gas injection unit are installed in a relatively rotating manner, the method comprising the steps of: putting the plurality of substrates on the substrate seat portions; simultaneously supplying the source gas, the reaction gas, and the mixed gas onto the substrate support unit through the gas injection unit; and feeding the source gas, the mixed gas, the reaction gas and the mixed gas sequentially on each of the plurality of substrate to deposit the thin film on the plurality of substrates while the substrate support unit and the gas injection unit relatively rotate, wherein two or more source gas suppliers are symmetrically disposed opposite to each other, the reaction gas supplier is disposed between the source gas suppliers, and the mixed gas supplier is disposed on at least one of the source gas supplier and the reaction gas supplier, wherein the source gas is a Ru source, and the reaction gas is an oxide gas, and wherein the Ru source is an organic compound including Ru, and the oxide gas is at least one selected from a group of O wherein a rate of the reaction gas to the inert gas in the mixed gas is in a range of 1 to 50%, and wherein the mixed gas is provided to the substrate to restrain growth of Ru and deposit a RuO
