Claim One:
1. An electron microscope, comprising: an input unit for capturing image data on a microscopic image acquired by another electron microscope; a memory unit for memorizing said image data on a pattern image of a photomask captured via said input unit; a computation processing unit configured for: manipulating said image data on said pattern image of a photomask memorized into said memory unit by executing at least an image-display-magnification modifying step and an image reversing step, in order that a display condition of the pattern image of the photomask and display condition of a pattern image on a wafer formed by using the photomask which is a microscopic image acquired by said electron microscope itself are caused to coincide with each other, and generating a display signal based on said image data on said pattern image of the photomask manipulated by said computation processing unit and image data on said pattern image on the wafer; and a display unit for displaying, based on said display signal from said computation processing unit, microscopic image manipulated by said computation processing unit and said pattern image on the wafer.
