Abstract: Disclosed is a scanning charged particle beam apparatus equipped with an aberration corrector, contrived to eliminate resolution degradation in tilt observation by a chromatic third-order aperture aberration without relying on a specific optical system. A controller of the scanning charged particle beam apparatus provides a chromatic third-order aperture aberration measurement method relevant to tilt observation of a specimen. Further, the controller has a chromatic aberration control function relevant to tilt observation of a specimen. By means of the chromatic aberration control function, the controller controls a chromatic aberration to be positive or negative, rather than remaining at 0, in order to eliminate an image blur which occurs in a direction parallel to the specimen surface due to a chromatic third-order aperture aberration and a chromatic aberration at a tilt angle (t1) under observation and another tilt angle (?t1) axially opposite to the tilt angle.

Abstract: Disclosed is an aberration measurement method of a charged particle beam device provided with an aberration corrector (4). The method is characterized by: when measuring aberration, (A) the number of pixels or the resolution is changed of a first image and a second image that are benchmarks when measuring field of view offset, and after determining the destination of movement resulting from a rough field of view offset, the number of pixels or the resolution of the first image and the second image are set to the same conditions, and the amount of field of view offset is measured precisely, or (B) a sample having lines in the horizontal direction and in the vertical direction is one-dimensionally scanned, and the amount of movement is measured from the signal position offset. As a result, in a charged particle beam device provided mounted with an aberration corrector, it becomes possible to provide a highly precise aberration measurement method that is not to the detriment of measurement time.
