Abstract:
This substitution site measuring equipment using an electron beam analyzes, with high precision, the structure of a substitution site in a micrometer- to nanometer-order region, by reducing or vanishing the X-ray intensity of diffraction X-rays generated in a specimen. The substitution site measuring equipment measures a substitution site in a crystal by detecting, by means of an X-ray detector, X-rays generated from a specimen upon irradiation of the specimen with an electron beam. The substitution site measuring equipment is provided with: an input unit to which a crystal structure of a specimen, energy or wavelengths of X-rays to be detected, a tilt angle of the specimen, and positional information about the specimen and the X-ray detector are inputted; a diffraction X-ray incidence calculating means for calculating incidence of diffraction X-rays on the X-ray detector on the basis of parameters inputted to the input unit; a measurement condition setting means for setting a measurement condition according to the incidence of diffraction X-rays on the X-ray detector calculated by the diffraction X-ray incidence calculating means such that the diffraction X-rays are not incident on the X-ray detector; and an electron beam inclination/X-ray detection control unit that detects the X-rays in synchronization with the inclination of an electron beam.

Claim (Index 8):
The substitution site measuring equipment according to  claim 1 ,\n wherein the X-ray detector is a position resolution X-ray detector including a plurality of X-ray detecting elements, the diffraction X-ray incidence calculating means includes: an X-ray diffraction calculation unit for calculating an X-ray diffraction angle on the basis of the crystal structure of specimen and the energy or wavelength of X-ray to be detected; and an incidence position calculation unit for calculating an incidence position of the diffraction X-ray on the X-ray detector on the basis of the calculated X-ray diffraction angle, the tilt angle of specimen and the positional information about the specimen and the X-ray detector, and the measurement condition setting means includes: a measurement object exclusion setting unit for excluding, from measurement, an X-ray detecting element on which the diffraction X-ray is incident; and an average setting unit for setting an X-ray signal value of the X-ray detecting element excluded by the measurement object exclusion setting unit to an average of X-ray detection amounts of its neighboring detecting elements.
