    • Charged-particle-beam (CPB) mapping projection-optical systems and adjustment methods for such systems are disclosed that can be performed quickly and accurately. In a typical system, an irradiation beam is emitted from a source, passes through an irradiation optical system, and enters a Wien filter (“E×B”). Upon passing through the E×B, the irradiation beam passes through an objective optical system and is incident on an object surface. Such impingement generates an observation beam that returns through the objective optical system and the E×B in a different direction to a detector via an imaging optical system. An adjustment-beam source emits an adjustment beam used for adjusting and aligning the position of, e.g., the object surface and/or the Wien's condition of the E×B. The adjustment beam can be off-axis relative to the objective-optical system. For such adjusting and aligning, fiducial marks (situated, e.g., in the plane of the object surface) can be used that are optimized for the CPB optical system and the off-axis optical system. Desirably, the image formed on the detector when electrical voltage and current are not applied to the E×B is in the same position as the image formed on the detector when electrical voltage and current are applied to the E×B. Also provided are “evaluation charts” for use in such alignments that do not require adjustment of the optical axis of the irradiation optical system, and from which the kinetic-energy distribution of the emitted adjustment beam is stable.
    • 公开了可以快速且准确地执行这种系统的带电粒子束(CPB)映射投影光学系统和调整方法。 在典型的系统中,照射光束从光源发射,通过照射光学系统,并进入维恩滤光片(“ExB”)。 当通过ExB时,照射光束通过物镜光学系统并入射到物体表面上。 这种冲击产生观察光束,该观察光束经由成像光学系统通过物镜光学系统和ExB以不同的方向返回到检测器。 调整光束源发射用于调整和对准例如物体表面的位置和/或ExB的维恩状态的调节光束。 调节光束可以相对于物镜光学系统偏轴。 对于这种调整和对准,可以使用为CPB光学系统和离轴光学系统优化的基准标记(例如位于物体表面的平面中)。 理想地,当电压和电流未施加到ExB时,在检测器上形成的图像与当将电压和电流施加到ExB时形成在检测器上的图像位于相同的位置。 还提供了用于这种对准的“评估图”,其不需要调整照射光学系统的光轴,并且发射的调节光束的动能分布从该距离稳定。
