摘要: An ion source for use in an ion implanter. The ion source includes a gas confinement chamber having conductive chamber walls that bound a gas ionization zone. The gas confinement chamber includes an exit opening to allow ions to exit the chamber. A base positions the gas confinement chamber relative to structure for forming an ion beam from ions exiting the gas confinement chamber. A supply of ionizable material routes the material into the gas confinement chamber. An antenna that is supported by the base has a metallic radio frequency conducting segment mounted directly within the gas confinement chamber to deliver ionizing energy into the gas ionization zone.
