Abstract
An ion implantation apparatus includes: a lens electrode unit including a plurality of electrode sections for parallelizing an ion beam; and a vacuum unit that houses the lens electrode unit in a vacuum environment. The vacuum unit includes: a first vacuum container having a first conductive container wall; a second vacuum container having a second conductive container wall; and an insulating container wall that allows the first vacuum container and the second vacuum container to communicate with each other and that insulates the first conductive container wall from the second conductive container wall. An insulating member is provided that insulates at least one electrode section of the lens electrode unit from at least one of the first conductive container wall and the second conductive container wall, and the insulating member is housed in the vacuum environment together with the lens electrode unit.
