Abstract: An object of the invention is to provide a method and apparatus for observing inside structures and a specimen holder, wherein aging degradation of a good sample to a bad sample can be tracked in the same field of view, using the same specimen in order to determine the mechanism of failure. The present invention is a method for observing inside structures. The method comprises irradiating a specimen with a corpuscular beam generated from a corpuscular beam source, detecting transmitted particles transmitted by the specimen, applying a voltage to a portion of the specimen, and observing of a detection status of the transmitted particles in the voltage-applied portion as needed.

Abstract: There is provided an element mapping unit, scanning transmission electron microscope, and element mapping method that enable to acquire an element mapping image very easily. On the scanning transmission electron microscope, the electron beam transmitted through an object to be analyzed enters into the element mapping unit. The electron beam is analyzed of its energy into spectrum by an electron spectrometer and an electron energy loss spectrum is acquired. Because the acceleration voltage data for each element and window data for 2-window method, 3-window method or contrast tuning method are already stored in a database and accordingly the spectrum measurement is carried out immediately even when an element to be analyzed is changed to another, the operator can confirm a two-dimensional element distribution map immediately.
