Abstract:
An ion implantation system, comprising:an ion source adapted to produce an ion beam along a path; a beamline assembly located downstream from the ion source, the beamline assembly comprising: a beamguide having at least one wall defining a passageway through which the ion beam is transported along the path; a magnetic device adapted to provide multi-cusped magnetic fields in the beamguide passageway; and a power source coupled with the beamguide to provide microwave electric fields in the beamguide passageway, wherein the microwave electric fields and the multi-cusped magnetic fields provide containment of the ion beam in the beamguide passageway; and an end station located downstream from the beamline assembly along the path, the end station being adapted to support a wafer along the path for implantation using the ion beam.
