摘要： 3-dimensional observation on the atomic arrangement and atomic species in a thin-film specimen as well as conventional electron microscope observations is carried out at high speed and accuracy by an electron microscope which measures electrons emitted at high angle from the specimen. For that purpose, the present invention provides a scanning transmission electron microscope having an electron detection device comprising a scintillator converting electrons detected thereby to photons, a photoconductive-film converting photons from the scintillator detected thereby to c.a. 1000 times as many electron-hole pairs as these photons (i.d. avalanche multiplication), an electron gun emitting an electron beam toward the photoconductive-film to detect the holes generated therein, and electron deflector electrodes deflecting the electron beam on the photoconductive-film. Avalanche multiplication in the photoconductive-film amplifies the signal of these photons at so high signal-to-noise ratio that the electron microscope in this invention can detect such weak electrons as emitted at high angle from the specimen at high sensitivity and resolution. Therefore this invention enables a scanning transmission electron microscope to obtain for example 3-dimensional image of point defects and impurity elements existing in joint interfaces and contacts in a ULSI device rapidly and accurately.

摘要： 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. Besides, because every electron beam that enters into an energy filter passes through the object point, aberration strain in the electron spectrometer can be minimized and higher energy stability can be achieved. As a result, drift of the electron energy loss spectrum acquired by analyzing the electron beam into spectrum can be minimized and element distribution with higher accuracy can be acquired.
