Patent ID: 7994488

Claim:
An ion implantation system comprising: an ion source configured to generate an ion beam along a beam path; a mass analyzer component downstream of the ion source configured to perform mass analysis on the ion beam; a resolving aperture downstream of the mass analyzer component configured to pass a portion of the ion beam traveling along a beamline axis; an endstation process chamber downstream of the resolving aperture, the endstation process chamber configured to rotate about the beam line axis, thereby defining an endstation workpiece axis therein; a deflection element downstream of the resolving aperture configured to change an angle of the ion beam exiting the deflection element, thereby deflecting the ion beam off of the beamline axis onto a deflection axis; a deceleration electrode downstream of the deflection element configured to decelerate the ion beam along the deflection axis; and a support platform configured to retain and position a workpiece for implantation of charged ions of the ion beam; wherein the deflection element and the deceleration electrode reside within the endstation process chamber, but do not rotate with the endstation process chamber, and wherein the support platform resides within the endstation process chamber and does rotate with the endstation process chamber.
