Abstract:
An ion beam implanter comprising:a) an ion beam source for generating an ion beam moving along a beam line; b) an implantation chamber having an evacuated interior region 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, the workpiece support structure including: 1) a chuck for holding the workpiece, the chuck including a rotatable pedestal supporting the workpiece; 2) a first rotatable reel coupled to and rotatable with the pedestal; 3) a flexible, hollow cord coupled to the first rotatable reel such that, as the pedestal is rotated in a first direction, a length of the flexible cord wrapped around the first reel increases and, as the pedestal is rotated in an opposite direction, a length of the flexible cord wrapped around the first reel decreases; and 4) facilities including at least one of a coolant line carrying coolant to the chuck and an electrical power conductor conducting electrical power or control signals to the chuck, at least a portion of the at least one of the coolant line and the electrical power conductor being routed through an interior of the cord.
