  • Patent number: 11862433
    Abstract: A system having an auxiliary plasma source, disposed proximate the workpiece, for use with an ion beam is disclosed. The auxiliary plasma source is used to create ions and radicals which drift toward the workpiece and may form a film. The ion beam is then used to provide energy so that the ions and radicals can process the workpiece. Further, various applications of the system are also disclosed. For example, the system can be used for various processes including deposition, implantation, etching, pre-treatment and post-treatment. By locating an auxiliary plasma source close to the workpiece, processes that were previously not possible may be performed. Further, two dissimilar processes, such as cleaning and implanting or implanting and passivating can be performed without removing the workpiece from the end station.
