Abstract:
The present invention enlarges a range of movement of field of view by beam deflection with a simple deflector configuration and suppresses deterioration of a signal electron detection rate caused by the beam deflection. A scanning electron microscope according to the present invention is provided with a first deflection field setting module that sets plural deflectors to move a scanning area on a specimen by a primary electron beam to a position deviated from an axis extended from an electron source toward the center of an objective lens and a second deflection field setting module that sets the plural deflectors so that trajectories of signal electrons are corrected without changing the scanning area set by the first deflection field setting module. The control unit controls the plural deflectors by adding a setting value set by the second deflection field setting module to a setting value set by the first deflection field setting module.

Claim (Index 11):
The scanning electron microscope according to  claim 7 , comprising:\n an electron beam deflector and a reflector on the axis, wherein the detector detects an electron generated by collision of the primary electron deflected by the electron beam deflector with the reflector; and when the control unit controls the plurality of deflectors by adding the setting value set by the second deflection field setting module to the setting value set by the first deflection field setting module, the signal electron is incident on the electron beam deflector along the axis as a result.
