离子注入装置、最终能量过滤器以及离子注入方法
摘要：
本发明提供一种能够广泛使用的离子注入装置及离子注入方法。本发明的最终能量过滤器(400)具备入口侧单透镜(304)、中间电极部(401)及出口侧单透镜(308)。最终能量过滤器(400)具备FEF电源部(414)，该FEF电源部构成为分别单独向入口侧单透镜(304)、中间电极部(401)及出口侧单透镜(308)施加电压。FEF电源部(414)分别向上游辅助电极部(402)、偏转电极部(306)及下游辅助电极部(404)施加电压，以使上游辅助电极部(402)与偏转电极部(306)之间的第1区域中的离子束的能量范围和偏转电极部(306)与下游辅助电极部(404)之间的第2区域中的离子束的能量范围成为相同程度。
摘要（英）：

A final energy filter includes a first adjustment electrode portion, an intermediate electrode portion, and a second adjustment electrode portion. The final energy filter further includes a power supply unit. The power supply unit is configured such that it applies the voltages separately to the first adjustment electrode portion, the intermediate electrode portion, and the second adjustment electrode portion. The power supply unit applies voltages to an upstream auxiliary electrode portion, a deflection electrode portion and a downstream auxiliary electrode portion, respectively, such that the energy range of ion beam in a first region between the upstream auxiliary electrode portion and the deflection electrode portion is approximately equal to that in a second region between the deflection electrode portion and the downstream auxiliary electrode portion.
