Abstract
There is provided a movable ion beam inclination-angle measuring apparatus that can measure the inclination angle of either a spot ion beam or a ribbon ion beam. The apparatus is provided in an X-axis direction from an ion supplying unit of an ion implantation device. The apparatus includes an ion current measuring unit which has an ion-beam receiving device for receiving the ion beam, and has an ion current measuring part for measuring an ion current induced by the received ion beam. The apparatus further includes an angle adjusting unit adapted to adjust a receiving angle of the ion beam receiving device about a Y-axis and/or Z-axis and a position adjusting unit adapted to move the ion-beam receiving device in a Z-axis direction. The inclination angle is calculated by an inclination-angle calculating unit using the variation of the measured ion current depending on the adjustment of the receiving angle of the ion beam.
