Ion implantation apparatus

摘要

An ion implantation apparatus is provided with first and second magnets arranged so as to face each other in a Y direction across a path for a ribbon-shaped ion beam. The first and second magnets cross a traveling direction of the ribbon-shaped ion beam. Each of the first and second magnets has a pair of magnetic poles on an inlet side and on an outlet side of the ion beam. The polarities thereof are opposite between the first magnet and the second magnet.
