    • The present invention has a subject to provide an apparatus that optimizes scanning in accordance with circumstances or purposes, reduces distortion of images, and improves throughput, image quality, and defect detection rate by controlling deflection of a charged particle beam in a stage tracking system. To solve this subject, an apparatus according to the present invention is an inspection apparatus for detecting abnormal conditions of an inspection target by irradiating the inspection target with the charged particle beam and detecting generated secondary electrons, including both a stage that moves continuously with the inspection target placed thereon and a deflection control circuit for providing a deflector with a scanning signal that causes the charged particle beam to scan repeatedly in a direction substantially perpendicular to a stage movement axis direction while the charged particle beam being deflected in the stage movement axis direction in accordance with a change in movement speed of the stage during movement of the stage.
    • 本发明提供一种根据情况或目的优化扫描的装置,减少图像的失真,并且通过控制在舞台跟踪系统中的带电粒子束的偏转来提高吞吐量,图像质量和缺陷检测率。 为了解决这个问题,根据本发明的装置是一种检查装置,用于通过用带电粒子束照射检查对象并检测产生的二次电子来检测检查对象的异常状况,包括两个检查阶段连续移动的阶段 目标物放置在其上,以及偏转控制电路,用于向偏转器提供扫描信号,该扫描信号使得带电粒子束在基本上垂直于载物台移动轴线方向的方向上反复扫描,同时带电粒子束在载物台移动轴线方向上偏转 根据舞台运动中舞台的移动速度的变化。
