SYSTEM FOR CONTROLLING RADICALS USING A RADICAL FILTER

Abstract:

Provided herein are approaches for controlling radicals in proximity to a wafer. In some embodiments, a system may include a radical source operable to generate radicals in proximity to the wafer, and a filter positioned between the radical source and the wafer, wherein the filter includes a first plate operable to control radicals generated by the radical source. The system may further include an ion source operable to deliver an ion beam to the wafer, wherein the ion beam passes outside the filter.
