20110067631 | ARC ION PLATING APPARATUS - An arc ion plating apparatus comprises a vacuum chamber, a rotary table for moving a substrate within the vacuum chamber vertically relative to its height direction, an arc evaporation source for bombardment for cleaning the surface of the substrate with metal ions, and an arc evaporation source for deposition group for depositing metal ions on the surface of the substrate. The arc evaporation source for deposition group is composed of a plurality of evaporation sources arranged so as to be opposite to the substrate set on the rotary table, and the arc evaporation source for bombardment is arranged so as to be opposite to the substrate, and formed so that its length in the height direction of the vacuum chamber is equal to the length between the upper and lower ends of the arc evaporation source for deposition group. According to such a structure, over temperature rise or abnormal discharge is hardly caused in the substrate at the time of bombardment, and process controllability is consequently enhanced. | 03-24-2011 |
