Publication number: 20220107280Abstract: Provided is a quantification method for evaluating the quality of a sample on the basis of a mirror electron image acquired by a mirror electron microscope. In this invention, a mirror electron image is expressed numerically through counting of the brightness values of each pixel composing the mirror electron image, the creation of a brightness histogram, and the calculation, from the distribution of the brightness histogram, of a standard deviation. If brightness contrast is formed on the mirror electron image by, for example, a scratch on or latent damage in a sample, because the brightness values of the pixels will fluctuate, there will be more variation in the brightness values than in an image obtained from a satisfactory sample with no defects, and this will result in the brightness values of the mirror electron image having a larger standard deviation.Type: ApplicationFiled: February 15, 2019Publication date: April 7, 2022Inventors: Kentaro OHIRA, Masaki HASEGAWA
