The present invention is directed to a switch circuit and method to quickly enable or disable the ion beam to a wafer within an ion implantation system. The beam control technique may be applied to wafer doping repaint and duty factor reduction. The circuit and method may be used to quench an arc that may form between high voltage electrodes associated with an ion source to shorten the duration of the arc and mitigate non-uniform ion implantations. The circuit and method facilitates repainting the ion beam over areas where an arc was detected to recover dose loss during such arcing. A high voltage high speed switching circuit is added between each high voltage supply and its respective electrode to quickly extinguish the arc to minimize disruption of the ion beam. The high voltage switch is controlled by a trigger circuit which detects voltage or current changes to each electrode. Protection circuits for the HV switch absorb energy from reactive components and clamp any overvoltages.

An ion beam is rapidly switched off during ion implantation on detecting a beam instability. The ion beam is generated or provided by a non-arc discharge based ion source, such as an electron gun ion source or an RF ion source. The ion beam is scanned across a workpiece from a starting location toward an ending location. During the scanning, one or more beam characteristics are monitored, such as beam current, beam flux, shape, and the like. An instability is detected when one or more of the beam characteristics deviate from acceptable values or levels. The ion beam is rapidly turned off on the detected instability.
