Abstract
Disclosed are a charged particle beam apparatus and a sample processing observation method, the method including: a sample piece formation process in which a sample is irradiated with a focused ion beam such that a sample piece is cut out from the sample; a cross-section processing process in which the sample piece support holds the sample piece and a cross section thereof is irradiated with the ion beam to process the cross section; a sample piece approach movement process in which the sample piece support holds the sample piece and the sample piece is moved to a position that is closer to an electron beam column than an intersection point of beam optical axes of the ion beam and an electron beam is; and a SEM image acquisition process in which the cross section is irradiated with the electron beam to acquire the SEM image of the cross section.
