    • An inspection device for reducing time loss incident to a detection device replacing operation, comprising a plurality of detection devices (11, 12) for receiving an electron beam emitted from a sample (W) to obtain image data representing the sample (W), a switching mechanism (M) for having one of the plurality of detection devices (11, 12) receive an electron beam, characterized in that the plurality of detection devices (11, 12) are disposed in the same container (MC). The plurality of detection devices (11, 12) each can be a combination of a detection device provided with an electronic sensor for converting an electron beam into an electric signal and another detection device provided with an optical sensor for converting an electron beam into light and then converting the light into an electric signal. The switching mechanism (M) may be a mechanical moving mechanism or an electron beam deflector.
    • 一种用于减少入射到检测装置更换操作的时间损失的检查装置,包括用于接收从样品(W)发射的电子束以获得表示样品(W)的图像数据的多个检测装置(11,12), 用于使所述多个检测装置(11,12)中的一个检测装置(11,12)接收电子束的切换机构(M),其特征在于,所述多个检测装置(11,12)设置在同一容器(MC)中。 多个检测装置(11,12)各自可以是设置有用于将电子束转换成电信号的电子传感器的检测装置和设置有用于将电子束转换成光的光学传感器的检测装置的组合, 然后将光转换成电信号。 切换机构(M)可以是机械移动机构或电子束偏转器。
