Abstract:
1. An arc ion plating apparatus, comprising: a vacuum chamber; a moving member for moving a substrate loaded within said vacuum chamber, said moving member being provided within said vacuum chamber and moving said substrate in the direction perpendicular to the height direction of said vacuum chamber; an arc evaporation source for bombardment for irradiating metal ions evaporated by arc discharge from a vertically extending surface of the arc evaporation source for bombardment with the surface of said substrate to clean the surface of said substrate, said arc evaporation source for bombardment being provided within said vacuum chamber; and an arc evaporation source for deposition for depositing metal ions evaporated by arc discharge from a vertically extending surface of the arc evaporation source for deposition on the surface of said substrate, said arc evaporation source for deposition being provided within said vacuum chamber, wherein said arc evaporation source for deposition comprises an arc evaporation source for deposition group composed of a plurality of said arc evaporation sources for deposition arranged in opposition to said substrate installed in said moving member without mutually overlapping in the height direction of said vacuum chamber, said arc evaporation source for bombardment comprises an arc evaporation source for bombardment group composed of at least one arc evaporation source arranged in opposition to said substrate without mutually overlapping in the height direction of said vacuum chamber, and the length in the height direction of the vertically extending surface of said arc evaporation source for bombardment is longer than the vertically extending surface of said arc evaporation source for deposition by an amount such that a metal ion irradiation quantity per unit length in the vertical direction of the vertically extending surface of the arc evaporation source for bombardment will not cause an abnormal discharge on the substrate at the time of bombardment.
