发明名称 In-situ cleaning of beam defining apertures in an ion implanter
摘要 A method for cleaning an ion implantation, comprising providing an ion implantation system, wherein the ion implantation system comprises one or more components having one or more contaminants disposed thereon. A process species is provided to the ion implantation system, wherein the process species is otherwise utilized to implant ions into a workpiece. Ions are formed from the process species, therein defining an ion source. An ion beam is then extracted from the ion source via an application of an extraction voltage to an ion extraction assembly associated with the ion source. The extraction voltage is further modulated, wherein a trajectory of the ion beam is oscillated within a predetermined range. The ion beam is consequently swept across the one or more components, thus substantially removing the one or more contaminants therefrom.
