In the secondary charged particle image mode, a secondary charged particle image is produced on the basis of a detection signal (518) caused by reflected charged particles or secondary charged particles (517) from the sample (6).

Abstract: Ordinary charged particle beam apparatuses have each been an apparatus manufactured for dedicated use in making observations in a gas atmosphere at atmospheric pressure or at a pressure substantially equal thereto. There have existed no devices capable of simply making observations using an ordinary high-vacuum charged particle microscope in a gas atmosphere at atmospheric pressure or at a pressure approximately equal thereto. Furthermore, ordinary techniques have been incapable of observing the same spot of the sample in such an atmosphere using a charged particle beam and light simultaneously.

Abstract: An electron microscope has a large depth of focus in comparison with an optical microscope. Thus, information is superimposed on one image in the direction of depth. Therefore, it is necessary to accurately specify the three-dimensional position and density of a structure in a specimen so as to observe the three-dimensional structure of the interior of the specimen by using the electron microscope. Furthermore, a specimen that is observed with the optical microscope on a slide glass is not put into a TEM device of the related art. Thus, performing three-dimensional internal structure observation with the electron microscope on a location that is observed with the optical microscope requires very cumbersome preparation of the specimen.
