| 摘要 |
An ion implantation apparatus includes a beamline device for transporting ions from an ion source to an implantation processing chamber. The implantation processing chamber includes a workpiece holder for mechanically scanning a workpiece with respect to a beam irradiation region. The beamline device may be operated under a first implantation setting configuration suitable for transport of a low energy/high current beam for high-dose implantation into the workpiece, or a second implantation setting configuration suitable for transport of a high energy/low current beam for low-dose implantation into the workpiece. A beam center trajectory being a reference in a beamline is equal from the ion source to the implantation processing chamber in the first implantation setting configuration and the second implantation setting configuration. |
