Abstract: An apparatus for manufacturing a semiconductor device may include a vacuum chamber, an electrostatic chuck (ESC), a cooler, an RF plate, a casing, a base plate and a gas supplier. The ESC may be arranged in the vacuum chamber. The cooler may be configured to cool the ESC. The RF plate may be arranged under the cooler. The casing may be configured to support the cooler. The base plate may be opposite to the RF plate to form an inner space together with the casing. The gas supplier may supply a gas having a low dew point to the inner space. Thus, a generation of the dew condensation at the very low temperature may be prevented so that a damage caused by a short, which may be generated by the dew condensation, may also be prevented.
