Zusammenfassung: | The present invention is to provide a showerhead and a substrate processing device, which can prevent reaction gas from being adsorbed on the inner wall or internal parts of a chamber. According to one embodiment of the present invention, the substrate processing device comprises: a chamber in which a process for a substrate is performed; a susceptor which is installed inside the chamber to support the substrate; and a showerhead which is installed on top of the susceptor. The showerhead includes: a plurality of inner injection holes formed in an inner region corresponding to an upper part of the substrate and spraying reaction gas downwards; and a plurality of outer injection holes formed in an outer region corresponding to the outer side of the inner region and spraying inert gas along the inner wall of the chamber.
