Ion implanter

摘要

An ion implanter for implementing ion implantation using mass-separated ions using a limited energy of less than 10 keV, locates the decelerator between the ion source and the mass separator, and the beam transport space provided between the ion source and the decelerator is maintained at a higher negative voltage so as to decelerate the ion beam in combination, ensuring a large-current ion beam in excess of 1 mA to be maintained on the surface of a target.
