Beschreibung
Zusammenfassung:	An apparatus includes: a vacuum container having a vacuum atmosphere for a film forming process on each substrate; a stage for heating the substrate mounted thereon; a shower head including a facing portion that faces the stage and ejection ports opened in the facing portion, which supplies a film-forming gas to the substrate through the ports so as to form a film on the substrate; a cleaning gas supply part for supplying a cleaning gas into the container to clean the interior of the container in a state where no substrate is accommodated in the container while the film forming process is applied on the each of the plurality of substrates; and a non-porous coating film for covering a base material constituting the shower head at least in the facing portion to form a surface of the shower head when the film-forming gas is supplied to each substrate.
