Abstract
A composite charged particle beam apparatus includes a first charged particle beam column that irradiates a thin sample with a first charged particle beam, and a second charged particle beam column that irradiates an irradiation position of the first charged particle beam on the thin sample with a second charged particle beam. A sample holder as a base stage disposed on a sample stage, a motor-driven rotation driving section, a rotation stand rotatable about a flip axis by the driving of the rotation driving section, and a TEM grid that holds the thin sample. The TEM grid is movable within a plane perpendicular to an observation surface of the thin sample together with the rotation stand by being reciprocally driven around the flip axis by the driving section.
