Abstract:
1. An ion beam implanter for directing an ion beam against a workpiece, the implanter comprising: a) an implantation station defining an evacuated implantation chamber, the workpiece supported within the implantation chamber; b) beam forming and directing apparatus defining an evacuated ion beam implanter interior region through which the ion beam passes on its way to the implantation station; c) a flexible bellows disposed between the implantation station and the beam forming and directing apparatus such that the implantation station is movable with respect to the beam forming and directing apparatus, the bellows defining an evacuated interior region though which the ion beam passes; and d) a flexible bellows liner positioned within the bellows interior region for collecting implantation byproducts generated during implantation of the workpiece to reduce a volume of implantation byproducts deposited on an interior surface of the bellows.
