Abstract
An ion implantation system and method are provided where an ion beam is tuned to a first process recipe. The ion beam is scanned along a scan plane at a first frequency, defining a first scanned ion beam. A beam profiling apparatus is translated through the first scanned ion beam and one or more properties of the first scanned ion beam are measured across a width of the first scanned ion, thus defining a first beam profile associated with the first scanned ion beam. The ion beam is then scanned at a second frequency, thus defining a second scanned ion beam, wherein the second frequency is less than the first frequency. A second beam profile associated with the second scanned ion beam is determined based, at least in part, on the first beam profile. Ions are subsequently implanted into a workpiece via the second scanned ion beam.
