摘要:
A method for reducing particle contamination during implantation of ions comprises providing an implantation system for implanting ions into a workpiece via an ion beam, wherein one or more components are under selective vacuum and have one or more contaminants in a first state disposed thereon. A gas is introduced to the implantation system, wherein the gas generally reacts with at least a portion of the one or more contaminants, therein transforming the at least a portion of the one or more contaminants into a second state The at least a portion of the one or more contaminants in the second state remain disposed on the one or more components, and wherein the at least a portion of the second state of the one or more contaminants generally does not produce particle contamination on the one or more workpieces.
