    • An ion implanting apparatus is provided. The ion implanting apparatus includes a beam scanner, a beam collimator and a unipotential lens which is disposed between said beam scanner and said beam collimator, and which includes first, second, third, and fourth electrodes arranged in an ion beam traveling direction while forming first, second, and third gaps, said first and fourth electrodes being electrically grounded, wherein positions of centers of curvature of said first and third gaps of said unipotential lens coincide with a position of a scan center of said beam scanner, and wherein a position of a center of curvature of said second gap of said unipotential lens is shifted from the position of the scan center of said beam scanner toward a downstream or upstream side in the ion beam traveling direction.
    • 提供离子注入装置。 离子注入装置包括光束扫描器,光束准直器和设置在所述光束扫描器和所述光束准直器之间的单能透镜,并且包括以离子束行进方向排列的第一,第二,第三和第四电极,同时形成第一 第二和第三间隙,所述第一和第四电极是电接地的,其中所述单能透镜的所述第一和第三间隙的曲率中心位置与所述光束扫描器的扫描中心的位置重合,并且其中, 所述单能透镜的所述第二间隙的曲率中心从所述光束扫描器的扫描中心的位置向离子束行进方向的下游侧或上游侧偏移。
