Abstract:
A method of observing a sample by a transmission electron microscope comprising:a step of inputting a first magnification for use in searching a field of view and a second magnification for use in recording; a step of setting a magnification of a transmission electron microscope to the first magnification; a step of imaging a transmission electron beam image of a sample held on a sample stage by imaging means and displaying the transmission electron beam image of the sample in the first magnification on an image display section; a step of computing and storing a sample stage coordinate of a subject of recording designated over the transmission electron beam image of the sample displayed on the image display section; a step of cutting an image of the subject of recording out of the transmission electron beam image of the sample in the first magnification and storing a cut-out image as a first image; a step of setting the magnification of the transmission electron microscope to the second magnification; a step of moving the sample stage to the stored sample stage coordinate of the subject of recording; a step of capturing the transmission electron beam image in the second magnification with the same number of pixels as the first image and storing a captured image as a second image; a step of computing a movement amount of between two images from a correlation intensity of the first and second images; a step of correcting a position of the transmission electron beam image in the second magnification with respect to the imaging means such that the movement amount is zero; and a step of recording the transmission electron beam image in the second magnification imaged by the imaging means.
