Patent ID: 7476855

Claim:
An ion implantation system, comprising: an ion source configured to form a beam of undifferentiated ions; an end station having a workpiece associated therewith; a mass analyzing magnet generally positioned between the ion source and the end station and configured to select a desired beam of ions having a path and a focal point associated therewith, wherein the undifferentiated ion beam generally enters the mass analysis magnet at an entrance thereof, and wherein the desired ion beam exits the mass analysis magnet at an exit thereof, and wherein the mass analysis magnet further comprises one or more of an entrance pole mechanism adjustably positioned proximate to the entrance of the mass analysis magnet and an exit pole mechanism adjustably positioned proximate to the exit of the mass analysis magnet, wherein the position of at least one of the entrance pole mechanism and exit pole mechanism generally determines the path and focal point of the desired ion beam; and a controller configured to selectively position one or more of the entrance pole mechanism and exit pole mechanism, therein generally controlling the path of the desired ion beam at the exit of the mass analysis magnet.
