Patent ID: 7217925

Claim:
A scanning electron microscope comprising: a cathode; a scanning deflector for scanning an electron beam generated from said cathode on a specimen; an objective lens for converging said electron beam on said specimen; a detector for detecting secondary electrons generated from said specimen; a display device for displaying an image of said specimen based on an output of said detector; a moving stage for moving said specimen; and a control device for displaying areas whose object of interest obtained from another device is automatically selected for fine adjustment on the display device, for calculating a corrected coordinate value of said object of interest obtained from another device by using a coordinate correcting expression for correcting an error between a coordinate of said another device and a coordinate of said moving stage, and for moving said moving stage based on said corrected coordinate value, wherein: said control device moves said moving stage and adjusts a position of said object so as to move said object of interest to an observing position being observed by said electron beam, and calculates a vector of misalignment with coordinates of said object whose position was adjusted.
