1. An apparatus for processing a gas, comprising:

  • a mounting part installed in a processing container having a vacuum atmosphere and on which a substrate is mounted;

    a first gas flow path in which a first gas is supplied from a first gas supply mechanism to an upstream portion of the first gas flow path, and a downstream portion of the first gas flow path is branched to form a plurality of first branch paths;

    a second gas flow path in which a second gas is supplied from a second gas supply mechanism to an upstream portion of the second gas flow path, and a downstream portion of the second gas flow path is branched to form a plurality of second branch paths;

    an annular mixing chamber to which a discharge path is connected; and

    a gas discharge part being configured to discharge a mixture gas supplied from the discharge path onto the substrate,wherein the annular mixing chamber includes a plurality of first positions separated from each other in a circumferential direction, each of downstream ends of the plurality of first branch paths being connected to each of the plurality of first positions; and

    a plurality of second positions separated from each other in the circumferential direction, each of downstream ends of the plurality of second branch paths being connected to each of the plurality of second positions, and is configured to generate the mixture gas by mixing the first gas and the second gas flowing from the first branch paths and the second branch paths into the discharge path.
