Patent ID: 7276712

Claim:
An ion beam implanter comprising: a) an ion beam source for generating an ion beam moving along a beam line; b) an implantation chamber wherein a workpiece is positioned to intersect the ion beam for ion implantation of an implantation surface of the workpiece by the ion beam; and c) workpiece support structure coupled to the implantation chamber and supporting the workpiece within an interior region of the implantation chamber, the workpiece support structure including: 1) a rotation member coupled to the implantation chamber for changing an implantation angle of the workpiece with respect to a portion of the ion beam within the implantation chamber; and 2) a translation member movably coupled to the rotation member and supporting the workpiece within the implantation chamber interior region for movement along a path of travel wherein at least some components of the translation member are disposed within a reduced pressure translation member chamber that is isolated from the implantation chamber interior region by a dynamic seal.
