Abstract:
A deposited film forming method of, while continuously conveying a belt-like member in a longitudinal direction thereof, passing the belt-like member through a film-forming chamber, one side of which is formed of the belt-like member and which is located in a vacuum-sealable reaction vessel, introducing a reactive gas into the film-forming chamber, evacuating the interior of the film-forming chamber by evacuation means to maintain the interior of the film-forming chamber at a given pressure, introducing a high-frequency power into the film-forming chamber to induce a plasma, and forming a deposited film on the belt-like member passing through the film-forming chamber,wherein on a side opposite to a deposited film forming side of the belt-like member that forms said one side of the film-forming chamber, there is provided discharge confining means always maintaining contact with said opposite side of the belt-like member while following a change in shape of the belt-like member to hermetically close gaps between the opposite side of the belt-like member and the discharge confining means, whereby the deposited film is formed in a state of reduced discharge leakage and sparks in the film-forming chamber.
