    • Inspection method and apparatus capable of observing or inspecting a liquid sample (20) well. An optical image of the sample and an image using a primary beam such as an electron beam (7) or charged particle beam can be obtained at the same time. The inspection apparatus has a film (32) including a first surface (32a) on which the liquid sample is held, a vacuum chamber (11) for reducing the pressure of an ambient in contact with a second surface (32b) of the film, primary beam irradiation means (1) connected with the vacuum chamber and irradiating the sample with a primary beam via the film, signal detection means (4) for detecting a secondary signal produced from a specimen (38) contained in the sample in response to the primary beam irradiation, and optical image acquisition means (27) for obtaining an optical image of the specimen. The primary beam irradiation means and optical image acquisition means are located on opposite sides of the film that acts to block the light.

    • Method and apparatus capable of well observing or inspecting a liquid sample (20). The apparatus, for example a scanning electrode microscope, can be maintained and serviced better than heretofore. The apparatus has a film (32) including a first surface (32a) to hold the liquid sample (20) thereon, a vacuum chamber (11) for reducing the pressure of an ambient in contact with a second surface (32b) of the film (32), primary beam irradiation means (1) connected with the vacuum chamber (11) and irradiating the sample with a primary beam (7) via the film (32), signal detection means (4) for detecting a secondary signal produced from the sample (20) in response to the beam irradiation (7), a partitioning plate (14) for partially partitioning off the space between the film (32) and the primary beam irradiation means (1) in the vacuum chamber (11), and a vacuum gauge (15) for detecting the pressure inside the vacuum chamber (11).
      Damage to the film is detected by a pressure increase inside the vacuum chamber. After detecting such a pressure increase the partitioning member is moved in the path of the irradiating beam in order to prevent sample material to spill into the irradiation means.
    • 方法和能够很好观察或检查的液体样品(20)装置。 的装置,例如扫描电极显微镜,可以维护和服务比以前更好。 该装置具有一个膜(32)包括第一表面(32A)以保持液体样品(20)在其上,在真空室(11),用于与膜的第二面(32B)减少接触的环境的压力 (32),主光束照射单元(1)与所述真空室(11)连接,并且经由膜照射主光束(7)的样品(32)中,信号检测器,用于检测从产生的次级信号的装置(4) 响应于所述光束照射(7)的样品(20),分隔板(14),用于在真空室中部分分隔从薄膜(32)和初级束照射设备(1)之间的空间(11), 和真空计(15),用于检测所述真空室(11)内的压力。 损坏膜是通过在真空室内部的压力增加来检测。 检测寻求的压力增加分隔构件设置在照射光束的路径移动,以防止样品材料溢出到照射装置之后。
