Abstract:
1. A substrate processing apparatus comprising: a reaction chamber having therein a plurality of substrates stacked to have a predetermined distance therebetween; a first gas supply system configured to supply one of a mixture of a silicon-containing gas and a chlorine-containing gas and a silicon/chlorine-containing gas into the reaction chamber; a second gas supply system configured to supply at least a carbon-containing gas and a reduction gas into the reaction chamber; a first gas supply nozzle installed and extending in a region where the plurality of substrates are stacked; a second gas supply nozzle extending in the region, the second gas supply nozzle being installed in a position different from that of the first gas supply nozzle; a first branch nozzle installed at the first gas supply nozzle in a direction parallel to a major surface of each of the plurality of substrates, the first branch nozzle being branched toward the second gas supply nozzle and including at least one first gas supply port; a second branch nozzle installed at the second gas supply nozzle in the direction parallel to the major surface of each of the plurality of substrates, second branch nozzle being branched toward the first gas supply nozzle, and including at least one second gas supply port; and a controller configured to control the first gas supply system and the second gas supply system to supply one of the mixture of the silicon-containing gas and the chlorine-containing gas and the silicon/chlorine-containing gas into the reaction chamber through the at least one first gas supply port and supply at least the carbon-containing gas and the reduction gas into the reaction chamber through the at least one second gas supply port such that a silicon carbide film is formed on each of the plurality of substrates, wherein the at least one first gas supply port and the at least one second gas supply port are installed adjacent to each other in a stacking direction of the plurality of substrates.
