Abstract:
A combined ion-source and target-sputtering magnetron apparatus, comprising:a sealed housing forming a vacuum chamber connected to a source of vacuum;at least one object to be treated located in said sealed housing;at least one target-sputtering magnetron located in said housing and having a target with sputterable surface opposite said at least one object; andat least one ion-beam source located in said housing and directing an ion beam onto said sputterable surface of said target-sputtering magnetron for producing sputtered particles, said ion beam falling onto said sputterable surface at an angle from 0 to 90.degree. to said surface, said at least one ion-beam source being a cold-cathode ion-beam source with drift to electrons in crossed electric and magnetic fields, said ion-beam source having a housing, an anode and a cathode located in said housing of said ion-beam source, a working medium supply means for supplying at least one working medium into said housing of said ion-beam source, said apparatus having a first direct current voltage source with a first positive-voltage terminal and a first negative-voltage terminal, said ion-beam source having a housing which is connected grounded, said first positive-voltage terminal being connected to said anode, and said first negative-voltage terminal being ground, said ion-beam source having an opening for exposing said at least one object to said sputterable surface and having a closed-loop configuration with an outer side and inner side, said inner side being tapered and diverges toward said sputterable surface, said inner side having a closed-loop ion-emmitting slit through which said ion beam is emitted an angel from 0 to 90.degree. onto said sputterable surface.
