    • An ion implantation apparatus including a resolving aperture-shutter assembly (31) placed in the ion beam path (18). The resolving aperture-shutter assembly includes a movable shutter (34) and a shutter housing surrounding the movable shutter (34). Selected ions in an ion beam path (18) pass through a hole (44) in movable shutter (34) when the movable shutter (34) is in a first position, and are blocked by the solid surfaces when the movable shutter (34) is in a second position. The enclosure (32, 33, 39) completely surrounds the movable shutter (34). The enclosure (32, 33, 39) includes a first aperture (42) aligned with the ion beam path (18) for allowing the selected ions to enter the enclosure and a second aperture (41) aligned with the ion beam path (18) for allowing the selected ions to exit the enclosure after passing through the hole (44) in the movable shutter.
    • 一种离子注入装置,包括放置在离子束路径(18)中的分辨孔径光阑组件(31)。 分辨孔径光阑组件包括活动快门(34)和围绕活动快门(34)的快门壳体。 当活动快门(34)处于第一位置时,离子束路径(18)中的选定离子通过活动快门(34)中的孔(44),并且当活动快门(34)被固定时被固体表面阻挡, 处于第二位置。 外壳(32,33,39)完全包围活动活门(34)。 外壳(32,33,39)包括与离子束路径(18)对准的用于允许所选择的离子进入外壳的第一孔(42)和与离子束路径(18)对准的第二孔(41) 用于允许所选择的离子在通过可移动快门中的孔(44)之后离开外壳。
