Abstract:
1. A charged particle beam apparatus comprising: a focused ion beam apparatus fabricating a sliced specimen by processing a specimen as well as observing the sliced specimen; a scanning electron microscope observing the sliced specimen; a gas-ion beam irradiation apparatus performing finishing processing by irradiating a gas-ion beam onto a surface of the sliced specimen; a specimen stage on which the sliced specimen is fixed and having at least one rotation axis; a specimen posture recognition means recognizing positional relation of the sliced specimen with respect to the specimen stage; and a specimen stage control means controlling the specimen stage based on a specimen posture recognized by the posture recognition means and an installation angle of a lens barrel of the gas-ion beam irradiation apparatus in order to allow an incident angle of the gas-ion beam with respect to the obverse or the reverse of the sliced specimen to be a desired value.
