摘要： A technique capable of improving the ability to observe a specimen using an electron beam in an energy region which has not been conventionally given attention is provided. This specimen observation method comprises: irradiating the specimen with an electron beam; detecting electrons to be observed which have been generated and have obtained information on the specimen by the electron beam irradiation; and generating an image of the specimen from the detected electrons to be observed. The electron beam irradiation comprises irradiating the specimen with the electron beam with a landing energy set in a transition region between a secondary emission electron region in which secondary emission electrons are detected and a mirror electron region in which mirror electrons are detected, thereby causing the secondary emission electrons and the mirror electrons to be mixed as the electrons to be observed. The detection of the electrons to be observed comprises performing the detection in a state where the secondary emission electrons and the mirror electrons are mixed. Observation and inspection can be quickly carried out for a fine foreign material and pattern of 100 nm or less.

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.
