<p><P>PROBLEM TO BE SOLVED: To realize a computing means which can optimize an amount of focal gap in STEM and which can erase a virtual image and receive a feedback of a condition by substantially shortening the period of time to obtain a computed image and by comparing an image of an electron microscope to the computed image right after observation in an observation method and an observation equipment by a scanning transmission electron microscope. <P>SOLUTION: The observation is performed by a scanning transmission electron microscope observation equipment equipped with a field emission electron gun, a convergence means to converge an electron ray emitted from the field emission electron gun onto a sample, a deflecting means to scan a convergence electron ray irradiating the sample, a projecting means to project a sample image, and a measuring means for a sample thickness. <P>COPYRIGHT: (C)2003,JPO</p> |
