    • PURPOSE:To prepare a cross-cut section of an optional part of a sample with high accuracy while observing it by a secondary electron image by using shape memory alloys capable of easily controlling stress to the sample in a sample cross-cut section preparing mechanism. CONSTITUTION:Shape memory alloys 5 are used in a cross-cut section preparing mechanism 4, and a sample 3 is arranged in the shape of being sandwiched by the two alloys 5. The sample 3 fixed by sample press-down springs 1 and sample fixing stands 2 is divided and cut by the mechanism 4, and after a cross-cut section is prepared, the alloys 5 are heated by heaters 6, and contract downward. At this time, the springs 1 are fixed to fixing plates 7, and a preparing cross-cut section sample can be observed. Motive power of a motor 8 is transmitted to a caterpillar 17 through shafts 9 and 10 gears 11, 12, 13, 14, 15 and 16, and the mechanism 4 can be moved to an optional part. Thereby, a cross-cut section or the like of a semiconductor film sample having high chemical activity can be observed without being influenced by pollution of the sample, and an optional part of the sample 3 can be accurately divided and cut.

    • PURPOSE:To detect a proper amount of X-ray by providing a rotatable or slidable X-ray passage preventive plate having a plurality of X-ray passing holes which have different hole diameters between a sample and an energy dispersion type X-ray analyzer. CONSTITUTION:Incident electrons 2 produced from a filament 1 is applied to a sample 5, thereby producing characteristic X-rays 6a, 6b, 6c. At that time, optimal conditions are selected in a CPU 13 from the information of a Faraday's cup 10 to transmit a signal to a motor 9, which passes through a D/A converter and an amplifier 15 to rotate the X-ray passage preventive plate 7. Thereby, the X-ray passing hole of a proper hole diameter is selected from the plural X-ray passage holes 16a, 16b, 16c, 16d made in the X-ray passage preventive plate 7. Excessive characteristic X-rays 6b, 6c are not detected by the energy dispersion type X-ray detector 8 but only the characteristic X-ray 6a is detected. As a result, the simultaneous analysis of the energy dispersion type X-ray analyzer and a wavelength dispersion type X-ray analyzer circuit can be performed.
