    • PROBLEM TO BE SOLVED: To accurately measure the sectional shape or three-dimensional shape of a sample without using any matching of feature points.
      SOLUTION: The signal strength of electron beams is detected by an electron detector 3 when the sample 7 is illuminated with an electron gun 1 when a tilt angle is equal to ϕ=0. A slope angle θ of a sample surface is calculated by an image processing section 6 based on the detection output. The sectional shape candidate of the sample is estimated from the calculation value. The signal strength of electron beams that are generated from the sectional shape candidate of the sample is estimated when the tilt angle is changed to ϕ=ϕ
      0 , and electron beams are applied to the sectional shape candidate of the estimated sample. The estimated result of the signal strength is compared with the signal strength of electron beams that is actually detected by the electron detector 3 when the tilt angle is changed to ϕ=ϕ
      0 , and the sectional shape of the sample where the comparison result is minimized is estimated, thus obtaining the three- dimensional shape of the sample from the estimation result.

    • PURPOSE:To enable the evaluation of 3-D dispersion and changes in the density of material, by varying the irradiation point of an electron beam quadratically in a fine range to perform an arithmetic processing of the detection values in the intensity of reflected electrons and energy dispersion of characteristic X rays. CONSTITUTION:Electron beams emitted from an electron beam 1 are focused on a measuring sample on a sample base 6 through a condenser lens 3 and an objective lens 4 and the sample base 6 is moved with a sample base driver 13 to vary the irradiation point of the electron beam quadratically in a fine range sequentially. The intensity of the reflected electrons are memorized into an auxiliary memory 15 through a reflected electron analyzer 7 and an arithmetic unit 12. On the other hand, energy dispersion and wavelength dispersion of characteristic X rays are memorized into the memory 15 respectively through an energy analyzer 29 and the arithmetic unit 11 and a wavelength analyzer 10 and an arithmetic unit 12. The arithmetic unit 14 determines the composition and concentration of elements from these memory data. Thus, secondary electrons, reflected electrons and characteristic X rays generate in this order from the shallower location thereby enabling the evaluation of 3-D dispersion and changes in the concentration.
