    Abstract: A charged particle beam apparatus includes an electron beam irradiation unit that irradiates a sample with electron beams along a first irradiation axis. A rotation stage holds the sample and has a rotation axis in a direction perpendicular to the first irradiation axis. An ion beam irradiation unit irradiates the sample with ion beams along a second irradiation axis that is substantially parallel to the rotation axis to process the sample into a needle shape. A detection unit detects at least one of charged particles and X rays generated via the sample by the irradiation with the ion beams or the electron beams, and a gaseous ion beam irradiation unit irradiates the sample with gaseous ion beams. A control unit controls the apparatus to incrementally rotate the rotation stage repeatedly by a predetermined angle to rotate the rotation stage by 360° in conjunction with irradiating the entire surface of the needle-shaped sample in a circumferential direction with the gaseous ion beams to remove ions implanted during processing the sample by the ion beams.

    Abstract: In a sample observation method, a sample stage is placed at a first tilt angle with respect to a charged particle beam, and an observation surface of a sample is irradiated with the charged particle beam to acquire a first charged particle image. The sample stage is then tilted to a second tilt angle different from the first tilt angle about a first sample stage axis, and the observation surface is again irradiated with the charged particle beam to acquire a second charged particle image. The sample stage is tilted to a tilt angle at which an area of the observation surface in the acquired charged particle image is the larger of the first charged particle image and the second charged particle image. The observation surface is then irradiated with the charged particle beam to observe the observation surface.
