Vacuum arc evaporation source and vacuum arc vapor deposition apparatus

Abstract

To provide an evaporation source and an arc evaporation apparatus in which an evaporation material as a cathode of arc discharge, and a magnetic field generating source arranged so that all lines of magnetic force crossing the evaporation surface of the evaporation material cross substantially vertically are arranged whereby the number of molten particles arriving at a substrate by the magnetic field can be reduced, and deviation of occurrence of arc spots can be suppressed.
