Abstract
Provided herein are approaches for reducing particles in an ion implanter. In some embodiments, an electrostatic filter of the ion implanter may include a housing and a plurality of conductive beam optics within the housing, the plurality of conductive beam optics arranged around an ion beam-line. At least one conductive beam optic of the plurality of conductive beam optics may include a conductive core element, a resistive material disposed around the conductive core, and a conductive layer disposed around the resistive material.
