摘要: Ions emitted from an ion source are dispersed by a dispersion means, and those ions of a predetermined mass number are extracted from the thus-dispersed ions and are selectively implanted into a sample. A plane of incidence of ions in the mass-dispersing means is so formed that the angle of incidence of ions thereon has a negative value, and a plane of emission of ions therein is so formed that the angle of emission of ions of the predetermined mass number therefrom has a positive value.
