Abstract
A focused ion beam apparatus includes an image generation unit that generates a sample image including location detection marks formed on a sample based on secondary charged particles generated from the sample by emission of a focused ion beam to the sample, and a display that which displays a sample image. A control unit which, in a case of performing working by emitting the focused ion beam to a working region of the sample that is beyond a display range, moves a sample stage, detects locations of the location detection marks included in the sample image after the movement of the sample stage as reference marks from the location detection marks included in the sample image before moving the sample stage, and controls an emission location of the focused ion beam based on the reference marks detected in the sample image after movement of the sample stage to correct a working location shift due to movement of the sample stage.
