The substrate processing apparatus and the method of processing an exhaust gas according to the present invention, an exhaust gas decomposition module may decompose a source gas exhausted from a process chamber to decompose a ligand of the source gas. Also, the ligand and the source gas of which the ligand has been decomposed may be put in a stabilized state by reacting with separately supplied O2, N2O, or O3, and then, may be changed to a mixed gas including a reactant gas mixed therewith. Subsequently, the mixed gas may flow into the exhaust pump and may be emitted. Alternatively, the ligand and the source gas may be mixed with the reactant gas and may be emitted. Therefore, the ligand and the source gas of which the ligand has been decomposed may not react with the reactant gas or heat which occurs in the exhaust pump, and thus, the ligand-decomposed source gas and the ligand flowing into the exhaust pump are not deposited on an inner surface of the exhaust pump. Also, the ligand-decomposed source gas and ligands piled in the exhaust pump are not exploded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Substrate processing apparatus having exhaust gas decomposer, and exhaust gas processing method therefor","description":"Disclosed is a substrate processing apparatus and the method of processing an exhaust gas.
