<p>A system and method are provided for implanting ions into a workpiece in a plurality of operating ranges. A desired dosage of ions is provided, and a spot ion beam is formed from an ion source and mass analyzed by a mass analyzer. Ions are implanted into the workpiece in one of a first mode and a second mode based on the desired dosage of ions, where in the first mode, the ion beam is scanned by a beam scanning system positioned downstream of the mass analyzer and parallelized by a parallelizer positioned downstream of the beam scanning system. In the first mode, the workpiece is scanned through the scanned ion beam in at least one dimension by a workpiece scanning system. In the second mode, the ion beam is passed through the beam scanning system and parallelizer un-scanned, and the workpiece is two-dimensionally scanned through the spot ion beam.</p> |
