Abstract:
1. A system for moving a wafer during scanning said wafer, comprising: an extendable/retractable arm, at least a length of said extendable/retractable arm parallel to a direction being adjustable; a holding apparatus, fixed on a specific portion of said extendable/retractable arm and capable of holding said wafer; a swing driving apparatus, capable of swinging said extending/retracting arm along another direction substantially perpendicular to both of a transmission path of an ion beam and an axis of said extendable/retractable arm, wherein an end of said extendable/retractable arm is pivoted via said swing driving apparatus, said extending/retracting arm being configured to be swung within a plane perpendicular to said transmission path of an ion beam, a swing direction not being a rotation direction, and the extendable/retractable arm being extendable within a plane of the swing; and a first driving apparatus, capable of extending and/or retracting said extendable/retractable arm such that said holding apparatus is moved with said specific portion.
