摘要： An inspection apparatus includes: beam generation means for generating any of charged particles and electromagnetic waves as a beam; a primary optical system that guides the beam into an inspection object held in a working chamber and irradiates the inspection object with the beam; a secondary optical system that detects secondary charged particles occurring from the inspection object; and an image processing system that forms an image on the basis of the detected secondary charged particles. The primary optical system includes a photoelectron generator having a photoelectronic surface. The base material of the photoelectronic surface is made of material having a higher thermal conductivity than the thermal conductivity of quartz. A central portion of the inspection object is provided with a central flat portion 390. The periphery of the central flat portion 390 is provided with peripheral flat portion 392 via a step 391. The periphery of the step 391 is provided with an electric field correction plate 400. A surface voltage equivalent to a surface voltage applied to the inspection object is applied to an electrode 401 on the electric field correction plate 400.

摘要： An electron beam inspection device includes: a primary electron optical system that irradiates the surface of a sample with an electron beam; and a secondary electron optical system that gathers secondary electrons emitted from the sample and forms an image on the sensor surface of a detector. An electron image of the surface of the sample is obtained from a signal detected by the detector, and the sample is inspected. A cylindrical member that is formed with conductors stacked as an inner layer and an outer layer, and an insulator stacked as an intermediate layer is provided inside a lens tube into which the secondary electron optical system is incorporated. An electron orbital path is formed inside the cylindrical member, and the members constituting the secondary electron optical system are arranged outside the cylindrical member.
