And also as an apparatus for executing the method for manufacturing substrate with a thin film, the present invention provides: An apparatus, comprising a film forming chamber with first and second stockers capable of storing in multi-stages substrate on which a film to be formed upstream and downstream of a film forming area, and a loading chamber and an unloading chamber provided upstream and downstream of said film forming chamber, respectively with a stocker capable of storing in multi-stages substrate on which a film to be formed, wherein said film forming chamber, said loading chamber and said unloading chamber have respectively an independent evacuation means to allow evacuation; and said film forming chamber has a film forming particle generation source, a means for passing the substrate on which a film to be formed through the film forming area, and means for taking out the substrate on which a film to be formed one after another from the first stocker into the passing means and further putting it from the passing means into the second stocker. The method for manufacturing substrate with a thin film of the present invention can continuously and efficiently produce large-sized substrate with a thin film, and is wasteless in the film forming area, having features that the productivity is several times higher compared to the conventional methods and that the production cost is very low.
Abstract:
The present invention is a plasma CVD device provided with a vacuum chamber, and a plasma CVD electrode unit and a substrate-holding mechanism inside the vacuum chamber. The plasma CVD electrode unit is provided with an anode, a cathode that Faces the anode at a distance, and a first gas supply nozzle for supplying gas so as to Pass through the plasma-generation space between the anode and cathode. The substrate-holding mechanism is disposed at a position where the gas passing through the plasma-generation space impinges. The length of the anode in the gas-supply Direction and the length of the cathode in the gas-supply direction are both longer than the distance between the anode and the cathode. Thus, a plasma CVD device that Makes it possible to increase gas decomposition efficiency and achieve high film deposition rate is provided.

An object of the present invention is to provide a method and an apparatus for producing a large sized filmed substrate such as a reflection preventive filter using a relatively small production facility. In a method for producing a filmed substrate according to the present invention, the thickness of a monitor film formed on a film forming monitor is measured by using the film forming monitor disposed outside of a film forming area or a movable film forming monitor and a film forming process is controlled based on a film thickness so measured to thereby form a film even on a film forming objective substrate having a size equal to the entirety of the film forming area. In addition, the method of the present invention can improve the degree of freedom in which the film forming objective substrate is disposed within the film forming area, whereby the productivity during the production process can also be improved.
