A semiconductor device manufacturing apparatus includes a chamber including a reaction space, a substrate disposing unit configured to dispose a substrate within the chamber, a first heating unit configured to optically heat the reaction space and disposed under the chamber, a second heating unit configured to heat the reaction space through resistive heating and disposed over the chamber, and a plasma generating unit configured to generate plasma in the reaction space. Since the apparatus generates the plasma using the plasma generating unit disposed over the chamber, the deposition process based on heating and the etch process based on the plasma can be simultaneously performed in one single chamber.
