  • Publication number: 20180355479
    Abstract: A film forming apparatus is provided for forming a film by revolving a substrate placed on a rotary table in a vacuum container, alternately supplying a precursor gas and a reaction gas that reacts with the precursor gas to generate a reaction product multiple times, and depositing the reaction product on the substrate. The film forming apparatus comprises a precursor gas supply region that supplies the precursor gas onto the substrate, one or more plasma generation regions that generate plasma at a position apart from the precursor gas supply region in a rotational direction of the rotary table, and a cleaning region that cleans the rotary table by supplying a cleaning gas onto the rotary table in a region apart from the plasma generation regions and the precursor gas supply region in the rotational direction when a film forming process is not performed on the substrate.
