The present invention relates to a substrate processing apparatus which includes a process chamber, a substrate supporting unit which is installed in the process chamber to support a plurality of substrates and rotates in a first rotation direction, a chamber lid covering the upper side of the process chamber, a source gas spray unit which is installed in the chamber lid and sprays a source gas to the substrate located in a source gas spray region, and a reducing agent spraying unit which is installed in the chamber lid in a position separated from the source gas spray unit along the first rotation direction and sprays the reducing agent reacting with the source gas on the substrate located in a reducing agent spray region via the source gas spray region. Accordingly, the present invention can increase the productivity of the substrate on which a deposition process is completed in case a thin film made of low reactant materials is deposited on the substrate.
