Abstract:
1. A charged particle beam apparatus comprising: an electron beam column configured to perform irradiation with electron beams; a sample stage configured to support a sample; a focused ion beam column configured to irradiate the sample with focused ion beams so as to form a cross-section; a scattered electron detector configured to detect backscattered electrons which are generated from the cross-section by the irradiation with the electron beams; a crystal orientation information generation unit configured to generate crystal orientation information on a predetermined region of the cross-section on the basis of the backscattered electrons; an angle calculation unit configured to calculate attachment angles of the sample stage, corresponding to a direction of the cross-section; and a display unit configured to display the crystal orientation information, wherein in response to receiving input of information indicating that the crystal orientation information on the region displayed on the display unit is changed to aimed second crystal orientation information,
