2. Description of the Related Art Vacuum vapor deposition
Is a film forming process in which a metal is heated and evaporated in a vacuum, and the evaporated metal is solidified on the surface of a substrate (material to be processed) to form a film. In such a film forming process, a continuous vacuum vapor deposition apparatus has been conventionally known in which an electron beam is used to heat a metal for vapor deposition (evaporation material) and vapor deposits the metal on a strip-shaped substrate that continuously runs. This continuous vacuum vapor deposition apparatus has the advantages that it can vapor deposit nitrides, carbides, oxides, etc., which cannot be handled by ordinary wet plating, and has a high deposition rate.

In the above-described vacuum vapor deposition apparatus, when a film is formed on a substrate having a wider width than before,
When the substrate is run at a high speed to form a film, it is necessary to increase the size of the crucible to increase the spread of vapor of vaporized metal and to increase the atomic number density of vapor of vaporized metal in the vapor deposition chamber. Therefore, it is necessary to increase the heating of the evaporated metal.
However, since heating with only the electron beam as described above requires a large electron gun, the vacuum vapor deposition apparatus also becomes large in size and equipment cost is required. Also, there is no electron gun of the required capacity. Further, when the intense electron beam is focused and irradiated, there is a problem that a temperature difference between the molten metal surface and the inside of the evaporated metal becomes large, so that a so-called bumping state occurs, and a splash easily occurs.
