Abstract:
The present disclosure relates to plasma generation systems particularly applicable to systems which utilize plasma for semiconductor processing. A plasma generation system consistent with the present disclosure includes an arc suppression device coupled to the RF generator. The arc device includes switches that engage upon a triggering signal. In addition, the arc device includes a power dissipater to be engaged by the set of switches to dissipate both stored and delivered energy when the set of switches engage. The arc suppression device also includes an impedance transformer coupled to the power dissipater to perform an impedance transformation that, when the switches are engaged in conjunction with the power dissipater, reduces the reflection coefficient at the input of the device. The plasma generation system further includes a matching network coupled to the radio frequency generator and a plasma chamber coupled to the matching network.
