Abstract

PURPOSE: To provide an electron beam type observing apparatus which can dispose an electron beam always on a position calibrated by a standard mark to precisely detect the position by utilizing high resolution of a scanning electron microscope.
CONSTITUTION: An electron beam is dispoded at a position 1a when measuring a specimen and at another position 1b when calibrating the position of the electron beam. A mark plate 2 for calibrating the position of the electron beam has a mark 3 for detecting the position, and is supported by a supporting station 5. A fine position control mechanism is provided among the station 5, a base and the mark plate 2. A specimen 4 to be measured is disposed on a table 6, and biaxially moved in X and Y directions to be observed. Mirrors 7, 8 are disposed on the station 5 and the table 4, respectively to determine the position of the specimen by a light wave interferometer. Then, electron beams 1a, 1b are independently biaxially deflected in X and Y directions within predetermined ranges to thereby detect a standard position detecting mark 3 so as to thus calibrate the displacements of the position.
