FEEDBACK LOOP FOR CONTROLLING A PULSED VOLTAGE WAVEFORM

Embodiments of this disclosure describe a feedback loop that can be used to maintain a nearly constant sheath voltage and thus creating a mono-energetic IEDF at the surface of the substrate. The system described herein consequently enables a precise control over the shape of IEDF and the profile of...
