  • Patent number: 11859286
    Abstract: A semiconductor manufacturing apparatus according to the present embodiment includes a first gas feeder, a first gas processor and a second gas feeder. The first gas feeder is provided above a stage on which a substrate is to be placed and feeds a first gas to the substrate. The first gas processor supplies high frequency power to the stage and renders the first gas fed from the first gas feeder into plasma. The second gas feeder is provided above the stage and feeds a second gas more difficult to render into plasma than the first gas to an outer periphery of the first gas having been rendered into plasma.
