Filed: 1987-08-07
Abstract: PURPOSE:To remove influence of reflex electrons etc., obstructive for inspection by synthesizing two image signals obtained through a grid bearing different potentials, in an inspection carried out through sensing of secondary electrons generated when electron beam is irradiated upon a specimen. CONSTITUTION:Secondary electrons 8 generated when an electron beam 4 is irradiated upon a specimen 2, are sensed by a sensor 7, and signals thus emitted serve the intended inspection. By irradiation of the electron beam, this sensor 7 senses, besides secondary electrons 8, such reflex electrons 9 as constituting obstacles to the inspection and also other secondary electrons 9a generated when these reflex electrons 9 collide with an objective lens 6 etc. A grid 11 made of electroconductive material is installed between the specimen 2 and the sensor 7. In case the grid 11 bears a certain negative value, the image will be a such in which secondary electrons 8 with weak energy do not reach the sensor. Synthesization of this image with an image with zero potential grid 11 gives a high precision image only with secondary electrons 8 from the difference between the two.
