Abstract: A method and apparatus for measuring the physical properties of a micro region measures the two-dimensional distribution of stress/strain in real time at high resolution and sensitivity and with a high level of measuring position matching. A sample is scanned and irradiated with a finely focused electron beam (23, 26), and the displacement of position of a diffraction spot (32, 33) is measured by a two-dimensional position-sensitive electron detector (13). The displacement amount is outputted as a voltage value that is then converted into the magnitude of the stress/strain according to the principle of a nano diffraction method, and the magnitude is displayed in synchronism with a sample position signal.
