Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The technique of arc suppression on the target surface of magnetron sputtering system during reactive
deposition of Al₂O₃ coatings has been developed. Damping of arcs is achieved by transient
polarity change of the magnetron voltage by means of a simple circuit consisting of a capacitor and
an inductive coil. Practically 100% arc inhibition probability is achieved during 5 - 20 мS after its
ignition. The energy input into arc before its disappearance is about 50-100 mJ. Results of experimental
and theoretical investigations of the arc suppression phenomenon are presented. Process of
the magnetron discharge transition to stationary state after the arc suppression has been studied too.
Relaxation oscillations of current and voltage accompanying this process are described. A theoretical
model of the non-stationary magnetron discharge is developed featuring its dynamic properties.
Magnetron discharge dynamic impedance is found. |
