Abstract

The present invention provides a high-energy ion injection device, which maintains the uniformity of injected ion density of a scanned high-energy ion beam, and improves the removability of foreign ions. The high-energy ion injection device comprises an irradiation beam generation unit, having an ion source and a quality analyzing device; a high frequency multi-segment straight line acceleration unit; a deflection unit, including a magnetic field energy analyzing device which carries out ion filtering using the momentum; an irradiation beam transmission line unit; and a substrate processing supplying unit. In the high-energy ion injection device, an electric field final energy filter which enable a high-energy scanning beam to deflect up and down through an electric field is also inserted between an electric field irradiation beam parallelizing device and a wafer, except for a magnetic quality analyzing device and an energy analyzing device used as a momentum filter, and the high frequency multi-segment straight line accelerating unit used as a speed filter.
