Abstract
(Task) To repeatedly perform an operation of extracting a sample piece formed by processing a sample with an ion beam and of transferring the extracted sample piece to a sample piece holder. (Problem Solving Means) A charged particle beam apparatus includes a computer that sets a shaping processing region including a bottom portion of sample piece in a thickness direction of the sample piece corresponding to a depth direction at the time of processing a sample after a needle holds the sample piece, and controls a focused ion beam irradiation optical system to irradiate the shaping processing region with a focused ion beam to thereby shape the sample piece.
