Abstract: Disclosed is a stage including a shaft, a first supporting plate over the shaft, a heater arranged in a trench formed in the first supporting plate, and a gas-supplying tube arranged in the shaft and configured to blow a gas to the first supporting plate. The first supporting plate may have a disk shape, and a cross section of the gas-supplying tube parallel to a surface of the first supporting plate may overlap a center of the disk shape. The first supporting plate may be configured to block the gas so that the gas is not released to a chamber in which the stage is arranged.
