Claim Text:
1. A charged particle beam apparatus comprising: an electron beam irradiation unit configured to irradiate a sample with electron beams along a first irradiation axis; a rotation stage, which is configured to hold the sample, and which has a rotation axis in a direction perpendicular to the first irradiation axis; an ion beam irradiation unit configured to irradiate the sample with ion beams along a second irradiation axis that is substantially parallel to the rotation axis so as to process the sample into a needle shape; a detection unit configured to detect at least one of charged particles and X rays generated via the needle-shaped sample by the irradiation with the ion beams or the electron beams; a gaseous ion beam irradiation unit configured to irradiate the needle-shaped sample with gaseous ion beams; and a control unit configured to control the charged particle beam apparatus to perform:
