Abstract:
A substrate processing apparatus comprising:a processing container, a substrate holding stand for holding a substrate-to-be-processed provided in the processing container, a first processing gas supply unit provided on a first side of the substrate holding stand in the processing container for supplying a first processing gas such that the first processing gas flows from the first side to a second side that counters the first side, the first processing gas flowing along the surface of the substrate-to-be-processed on the substrate holding stand, a first exhaust opening provided on the second side of the substrate holding stand in the processing container, a second processing gas supply unit provided on the second side of the substrate holding stand in the processing container for supplying a second processing gas that is different from the first processing gas such that the second processing gas flows from the second side to the first side, the second processing gas flowing along the surface of the substrate-to-be-processed on the substrate holding stand, a second exhaust opening provided on the first side of the substrate holding stand in the processing container, a first exhaust volume adjustment valve mechanism that connects the first exhaust opening to an exhaust apparatus, and a second exhaust volume adjustment valve mechanism that connects the second exhaust opening to the exhaust apparatus.
