Abstract

An ion implantation system may include an ion source to generate an ion beam, a substrate stage disposed downstream of the ion source; and a deceleration stage including a component to deflect the ion beam, where the deceleration stage is disposed between the ion source and substrate stage. The ion implantation system may further include a hydrogen source to provide hydrogen gas to the deceleration stage, wherein energetic neutrals generated from the ion beam are not scattered to the substrate stage.
