Abstract:
A multi charged particle beam inspection apparatus includes a plurality of sensors, arranged inside or on a periphery of a secondary electron image acquisition mechanism, to measure a plurality of interfering factors, a determination circuit to determine, for each interfering factor, whether change exceeding a corresponding threshold is a first case which returns to the original state within a predetermined time period, or a second case which does not return to the original state even if the predetermined time period has passed, and a comparison circuit to input a reference image of a region corresponding to the secondary electron image acquired, and compare the secondary electron image with the reference image, wherein in the case where change of the second case occurs, the secondary electron image acquisition mechanism suspends the acquisition operation of the secondary electron image, and calibrates a change amount of the multiple charged particle beams.

Claim (Index 4):
The apparatus according to  claim 1 , wherein, in a case where change of the first case occurs, the secondary electron image acquisition mechanism suspends the acquisition operation of the secondary electron image, and restarts the acquisition operation of the secondary electron image after the predetermined time period has passed, without calibrating a change amount of the multiple charged particle beams.
