摘要: An ion implantation apparatus includes a scanning unit, the scanning unit including a scanning electrode device that allows a deflecting electric field to act on an ion beam incident along a reference trajectory and scans the ion beam in a horizontal direction, and an upstream electrode device provided upstream of the scanning electrode device. The scanning electrode device includes a pair of scanning electrodes provided to face each other in the horizontal direction with the reference trajectory interposed therebetween and a pair of beam transport correction electrodes provided to face each other in a vertical direction perpendicular to the horizontal direction with the reference trajectory interposed therebetween. Each of the pair of beam transport correction electrode includes a beam transport correction inlet electrode body protruding toward the reference trajectory in the vertical direction in the vicinity of an inlet of the scanning electrode device.
