摘要： There is disclosed a charged particle beam device which judges whether or not an image based on a dark-field signal has an appropriate atomic number contrast. Input reference information, a bright-field image or a back-scattered electron image is compared with a dark-field image, and it is judged whether or not a correlation value between them or the dark-field image has a predetermined contrast. According to such a constitution, it is possible to obtain information by which it is judged whether or not the dark-field image has an appropriate atomic number contrast.

摘要： A sample image display method and an image shift sensitivity measuring method to be executed in a charged particle beam apparatus are provided for accurately correcting an image drift in any observing and analyzing condition such as an accelerating voltage, a working distance or a raster rotation. When obtaining a reference image used for detecting a drift, the process is executed to obtain an image having the different image shift amount from that of the reference image at a time and to occasionally measure an image shift sensitivity. Then, the process is executed to automatically register this reference image and the image shift sensitivity and to detect a drift amount and control an image shift (correct a drift) according to the registered conditions when correcting the drift.

摘要： A charged particle beam apparatus is provided which can prevent the accuracy of positional shift detection from being degraded owing to differences in picture quality, so that even when the state of a charged particle beam is changed at the time that optical conditions are changed or the optical axis changes with time, an auto adjustment of the optical axis can be realized easily and highly accurately. In the charged particle beam apparatus, evaluation or adjustment of focusing is conducted before the deflection condition of an alignment deflector for optical axis adjustment is changed or a table of focus adjustment amounts in correspondence with deflection conditions of the alignment deflector is provided, whereby when the deflection condition of the alignment deflector is changed, a focus adjustment is carried out in accordance with the table.

摘要： A charged particle beam apparatus facilitating adjusting a beam center axis of a charged particle beam in a case where optical conditions are modified or in a case where the beam center axis of the charged particle beam is moved due to state variation of the apparatus. When the beam center axis of a primary charged particle beam is adjusted with a deflector (aligner), a first processing step for measuring the sensitivity of the aligner and a second processing step for detecting the deviation between the center of the primary charged particle beam and the center of the objective aperture are provided. The charged particle beam apparatus determines the aligner set values, using the aligner sensitivity measured in the first processing step and the amount of deviation detected in the second processing step, such that the primary charged particle beam passes through the center of the objective aperture and controls the aligner using the aligner set values.
