Abstract: An ion implantation apparatus includes a first angle measuring instrument configured to measure angle information on an ion beam in a first direction, a second angle measuring instrument configured to measure angle information on the ion beam in a second direction, a relative movement mechanism configured to change relative positions of the first angle measuring instrument and the second angle measuring instrument with respect to the ion beam in a predetermined relative movement direction, and a control device configured to calculate angle information on the ion beam in a third direction perpendicular to both a beam traveling direction and the relative movement direction based on the angle information on the ion beam in the first direction measured by the first angle measuring instrument and the angle information on the ion beam in the second direction measured by the second angle measuring instrument.

Abstract: A vertical profile, a horizontal profile, and an integrated current value of an ion beam are measured by a plurality of stationary beam measuring instruments and a movable or stationary beam measuring device. At a beam current adjustment stage before ion implantation, a control device simultaneously performs at least one of adjustment of a beam current to a preset value of the beam current, adjustment of a horizontal beam size that is necessary to secure uniformity of the horizontal ion beam density, and adjustment of a vertical beam size that is necessary to secure the uniformity of the vertical ion implantation distribution on the basis of a measurement value of the stationary beam measuring instruments and the movable or stationary beam measuring device.
