Abstract:
1. An apparatus for scanning a workpiece through an ion beam, comprising: an elongated member having a workpiece chuck at a first end, for mounting a workpiece to be processed; a rotational mechanism mounting the elongated member at a point of rotation located on the elongated member away from the first end, and adapted to repetitively scan the workpiece through the ion beam along an arcuate path; a slow-scan mechanism suspending the elongated member and rotational mechanism, and adapted to cause movement of the rotational mechanism and the elongated member, to cause different portions of the workpiece to pass through the ion beam, wherein the elongated member comprises at least one opening located between the first end and the point of rotation, and facing the incoming ion beam, the at least one opening allowing passage of the ion beam through the elongated member.
