Abstract

Provided is a plasma processing system comprising: a plasma reactor generating plasma by receiving an input gas; and a radio frequency generator supplying radio frequency. The radio frequency generator supplies radio frequency power for plasma generation to the plasma reactor, wherein upon power interruption within a predetermined time occurring during the operation of the plasma reactor, the radio frequency generator re-supplies the radio frequency power, without discontinuing the operation of the plasma reactor, after power returns. Thereby, the plasma reactor stably maintains plasma upon momentary power interruption.
