    摘要: It is predicted that an observational direction (or an incident direction of an electron beam) in an observed image actually obtained has some errors compared to a set value. The error portion affects the analysis of the observed image later. Therefore, a convergent electron beam is irradiated on a specimen with a known shape, electrons discharged from the specimen surface are detected, an image of the electron is obtained, an incident direction of the convergent electron beam is estimated based on a geometric deformation on an image of the specimen with a known shape, and a 3D shape or a shape of a cross section of a specimen to be observed from a SEM image of the specimen to be observed is obtained by use of the information of the incident direction of the estimated convergent electron beam.

    摘要: A method and device for observing a specimen, in which a convergent electron beam is irradiated and scanned from a desired direction, on a surface of a calibration substrate on which a pattern with a known shape is formed, and a beam SEM image of the pattern formed on the calibration substrate is obtained. An actual direction of the electron beam irradiated on the surface of the calibration substrate is calculated by use of the information about an apparent geometric deformation of the known shape on the SEM image, and the actual direction of the electron beam to the desired is adjusted direction by using information of the calculated direction. The pattern with the known shape formed on the calibration substrate has a crystal plane formed by anisotropic chemical etching

    摘要: A method and device for observing a specimen in which an electron beam is irradiated and scanned from an oblique direction, onto a surface of a calibration substrate on which a pattern with a known shape is formed, and an SEM image of the surface of the calibration substrate is obtained. An angle in an oblique direction of the electron beam irradiated is obtained and is adjusted to a desired angle. The electron beam is irradiated from the adjusted desired angle in the oblique direction, onto a specimen substrate on which a pattern is formed, and an SEM image of the specimen substrate is obtained. The SEM image of the specimen substrate is processed by use of the information of the desired angle, and a 3D image of the pattern on the specimen substrate or a shape of a cross section of the pattern is obtained.

    摘要: Conventionally, defect data outputted by an inspection system comprised only characteristic quantitative data, such as coordinate data, area, and projected length, and only the coordinate data for moving to a defect location could be utilized effectively. By contrast, the present invention, by using image data in addition to characteristic quantitative data as the defect data for an inspection system, enables the retrieval of image data via an outside results confirmation system. Further, in the case of defect data of a plurality of substrates, it is enabled to display a defect image during inspection by the fact that similar defects are retrieved via images and retrieval results are displayed as trends makes it possible to display a defect image during inspection by searching similar defects on images and displaying them as a trend, designating a substrate on the trend, thereby displaying the defect map thereof and designating a defect on the defect map.
