Abstract: Provided are apparatuses for manufacturing semiconductor devices. An apparatus includes a reaction chamber having a stage to be loaded on a substrate, wherein set plasma is formed over the stage, a plurality of gas supply lines connected to the reaction chamber, flow controllers formed on the plurality of gas supply lines, respectively, to control the amount of a gas supplied to the reaction chamber, and a gas splitter configured to supply a mixed gas to the flow controllers. The apparatus may be a thin film deposition apparatus using plasma and further include a flow control unit connected to the gas splitter and a gas supply source connected to the flow control unit.
