    摘要: A sample evaluation/process observation system includes a common sample stage which accommodates a plurality of samples to be processed. The common sample stage is provided with a processing/observing notch and also with a movement mechanism. The movement mechanism functions to sequentially move the plurality of samples to the notch to cause the samples to be exposed to a predetermined processing beam and observing beam. The system further includes a beam processing device in which the common sample stage can be mounted and which functions to irradiate the predetermined processing beam on the plurality of samples through the notch to thereby sequentially perform beam processing operation over the samples. The system further includes a beam observation device in which the common sample stage can be mounted and which functions to irradiate the predetermined observing beam on the plurality of samples through the notch to sequentially observe and evaluate shapes of the plurality of samples. A mark is formed on one sample by a focused ion beam device so that positioning of the mark realizes automatic processing of a part of the sample to be processed. Further, the common sample stage is used in a high-acceleration transmission electron microscope and a high-acceleration scanning electron microscope and focused ion beam device.

    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.
