摘要： A system for further enhancing speed, i.e. improving throughput in a SEM-type inspection apparatus is provided. An inspection apparatus for inspecting a surface of a substrate produces a crossover from electrons emitted from an electron beam source 25•1, then forms an image under a desired magnification in the direction of a sample W to produce a crossover. When the crossover is passed, electrons as noises are removed from the crossover with an aperture, an adjustment is made so that the crossover becomes a parallel electron beam to irradiate the substrate in a desired sectional form. The electron beam is produced such that the unevenness of illuminance is 10% or less. Electrons emitted from the sample W are detected by a detector 25•11.

摘要： An inspecting apparatus for reducing a time loss associated with a work for changing a detector is characterized by comprising a plurality of detectors 11, 12 for receiving an electron beam emitted from a sample W to capture image data representative of the sample W, and a switching mechanism M for causing the electron beam to be incident on one of the plurality of detectors 11, 12, where the plurality of detectors 11, 12 are disposed in the same chamber MC. The plurality of detectors 11, 12 can be an arbitrary combination of a detector comprising an electron sensor for converting an electron beam into an electric signal with a detector comprising an optical sensor for converting an electron beam into light and converting the light into an electric signal. The switching mechanism M may be a mechanical moving mechanism or an electron beam deflector.
