Claim:
1. A charged particle beam device comprising: a charged particle source that emits a charged particle beam; a charged particle optical system that irradiates the charged particle beam on a sample; an EBSD detector that detects backscattered electron diffraction generated from a surface of the sample by irradiation of the charged particle beam; a sample stage that supports and moves a sample table on which the sample is disposed; an image display unit that displays a portion in the sample that is analyzable by the EBSD detector and a portion that is non-analyzable such that the portions are distinguishable; a user interface with which a position to be analyzed by the EBSD detector is input; and a computer programmed to control a planar movement, a tilt movement, and a rotational movement of the sample stage so as to allow the analysis position input from the user interface to be analyzed by the EBSD detector.
