    摘要: In a SEM device which enables observations under an atmospheric pressure, in the event that a diaphragm is damaged during an observation of a sample, air flows into a charged particle optical barrel from the vicinity of the sample, due to the differential pressure between the inside of the charged particle optical barrel under vacuum and the vicinity of the sample under the atmospheric pressure. At this time, the sample may be sucked into the charged particle optical barrel. In this case, a charged particle optical system and a detector are contaminated thereby, which causes performance degradation or failures of the charged particle microscope. For coping therewith, it is necessary to prevent the charged particle optical barrel from being contaminated, without inducing a time lag, with a simple structure. In a charged particle beam device adapted to place a sample in a non-vacuum environment, there is provided a filter member which is placed on the path of a primary charged particle beam at least in a state where the primary charged particle beam is directed to the sample and, further, is adapted to transmit or pass, therethrough, the primary charged particle beam and secondary charged particles derived from the sample, while intercepting at least a portion of a scattering substance which is scattered in the event of a fracture of the diaphragm.

    摘要: In a charged particle beam device that performs observation of a sample under a gas environment in atmospheric pressure or pressure substantially equal to the atmospheric pressure, a diaphragm that separates an atmospheric pressure space, in which the sample is placed, and a vacuum space in an interior of an electron optical lens barrel is made very thin in order to allow an electron beam to transmit therethrough and damaged with a high possibility. Although at the time of replacing the diaphragm, it is necessary to adjust a position of a diaphragm, it is impossible to easily perform the adjustment of the position of the diaphragm by a conventional method. In a charged particle beam device with a configuration in which a thin film that separates a vacuum environment and an atmospheric environment or a gas environment is employed, a detachable diaphragm that partitions a space, in which a sample is placed, in such a manner that pressure in the space in which the sample is placed is maintained at a level larger than pressure in an interior of a housing, and that allows transmission or passage of a primary charged particle beam therethrough, and a movable member that can move the diaphragm in a state where the pressure in the space, in which the sample is placed, and the pressure in the interior of the housing are maintained as they are, are provided.
