Patent ID: 8450220

Claim:
A substrate processing apparatus comprising: a reaction chamber configured to process a plurality of substrates stacked at predetermined intervals; a magnetic field generating unit installed outside the reaction tube and generating a magnetic field; a heating target object installed between the reaction tube and the magnetic field generating unit, the heating target object being configured to heat an inside of the reaction chamber by the magnetic field generated by the magnetic field generating unit; a first gas supply system configured to supply at least a gas containing silicon atoms and a gas containing chlorine atoms, or a gas containing silicon atoms and chlorine atoms; a second gas supply system configured to supply at least a reducing gas; a third gas supply system configured to supply at least a gas containing carbon atoms; a first gas supply nozzle connected to the first gas supply system and extending within the reaction chamber in a stacked direction of the plurality of substrates, the first gas supply nozzle comprising one or more first gas supply inlets in a region where the plurality of substrates are stacked; a second gas supply nozzle connected to the second and third gas supply systems and extending within the reaction chamber in the stacked direction, the second gas supply nozzle comprising one or more second gas supply inlets in the region where the plurality of substrates are stacked; and a controller configured to control: the first gas supply system to supply at least the gas containing silicon atoms and the gas containing chlorine atoms, or at least the gas containing silicon atoms and chlorine atoms into the reaction chamber through the first gas supply inlets of the first gas supply nozzle; the second gas supply system to supply at least the reducing gas into the reaction chamber through the second gas supply inlets of the second gas supply nozzle; and the third gas supply system so as to supply at least the gas containing carbon atoms into the reaction chamber through the second gas supply inlets of the second gas supply nozzle, so as to form silicon carbide films on the substrates.
