Abstract:
1. A vacuum deposition apparatus comprising: a deposition chamber; at least two magnetic-field applying mechanisms arranged in the deposition chamber, the at least two magnetic-field applying mechanisms being selected from the group consisting of a magnetic-field applying mechanism possessed by a sputtering evaporation source and a magnetic-field applying mechanism possessed by an arc evaporation source; and a magnetic-field shielding unit made from a magnetic material and arranged so as to cover partially or entirely at least one of the magnetic-field applying mechanisms, wherein the magnetic-field shielding unit can be movable between an open and a closed position, and wherein part of the magnetic-field shielding unit comprises a non-magnetic material arranged such that lines of magnetic force are able to pass through the magnetic-field shielding unit at the location of the non-magnetic material, and wherein the non-magnetic material is arranged such that the magnetic-field shielding unit shields the magnetic field when the magnetic-field shielding unit is at the closed position, and the shape and strength of the magnetic lines of force are greater when the magnetic-field shielding unit is at the open position.
