摘要: A circuit pattern inspection method and an apparatus therefor, in which the whole of a portion to be inspected sample is made predetermined charged state, irradiated with image-forming high-density electron beam while scanning beam, secondary particles are detected at after period time from instance when irradiated, image formed on basis thus particle signal, by using image.
