Method of detecting arc discharges in a plasma process
An arc discharge detection device is used for detecting arc discharges in a plasma process. The arc discharge detection device includes a comparator to which an instantaneous signal and a reference value are supplied. The reference value is formed by a setting means from an extreme value of the sign...

| description | An arc discharge detection device is used for detecting arc discharges in a plasma process. The arc discharge detection device includes a comparator to which an instantaneous signal and a reference value are supplied. The reference value is formed by a setting means from an extreme value of the signal. The extreme value is determined by an extreme value detection device within a predetermined time period, and the comparator changes the state of an arc discharge detection signal when the comparison between the reference value and an instantaneous value of the signal shows that an arc discharge has occurred. |
