Abstract

PROBLEM TO BE SOLVED: To prevent the adhesion of slashes to a substrate by shutting a shutter for preventing splash adhesion disposed below the substrate when the splashes are generated during the vapor deposition in a vacuum film forming chamber. SOLUTION: This device prevents the adhesion of the splashes which are generated from a crucible 11 and adhere to the substrate 3 in a continuous vacuum vapor deposition apparatus 1 for vapor depositing the material 12 to be evaporated on the band-shaped substrate 3 continuously traveling in a vacuum chamber. The thin flat planar splash adhesion preventive shutter broader than the substrate is rapidly openably and closably disposed between the crucible and the substrate above the crucible. A splash detector is disposed below the splash adhesion preventive shutter.
