A Re-igniting Device for Vacuum Arc Plasma Source    

A method and apparatus for automatically re-igniting vacuum arc plasma source.


The technology relates to methods for automatically re-igniting a vacuum arc (DC or long pulse AC) plasma source by monitoring the increase of main power supply voltage. The re-ignition signal will be sent to cathode when voltage exceeds certain level just before the arc completely extinguishes.

This technology sustains a continuous vacuum arc plasma source. It enhances vacuum arc deposition by minimizing pressure fluctuations in the deposition process. A mechanical trigger is not required.

Primary Application of the Technology

Plasma immersion ion implantation, vacuum arc plasma source
