摘要： In a scanning electron microscope, an atmospheric pressure space having a specimen arranged therein and a vacuum space arranged on a charged particle optical system side are isolated from each other using an isolation film that transmits charged particle beams. The scanning electron microscope has an electron optical lens barrel, a chassis, and an isolation film. The electron optical lens barrel radiates a primary electron beam onto a specimen. The chassis is directly bonded to the inside of the electron optical lens barrel and has an inside that turns into a lower vacuum state than the inside of the electron optical lens barrel at least during the radiation of the primary electron beam. The isolation film isolates a space in an atmospheric pressure atmosphere having a specimen mounted therein and the inside of the chassis in a lower vacuum state, and transmits the primary charged particle beam.

摘要： Provided is a charged particle beam apparatus or charged particle microscope capable of observing an observation target sample in an air atmosphere or a gas environment without making significant changes to the configuration of a conventional high vacuum charged particle microscope. In a charged particle beam apparatus configured such that a thin film (10) is used to separate a vacuum environment and an air atmosphere (or a gas environment), an attachment (121) capable of holding the thin film (10) and whose interior can be maintained at an air atmosphere or a gas environment is inserted into a vacuum chamber (7) of a high vacuum charged particle microscope. The attachment (121) is vacuum-sealed and fixed to a vacuum partition of the vacuum sample chamber. Image quality is further improved by replacing the atmosphere in the attachment with helium or a light-elemental gas that has a lower mass than atmospheric gases such as nitrogen or water vapor.

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.
