Abstract:
Charging areas in electron microscopy are identified by comparing images obtained in different frames. A difference image or one or more optical flow parameters can be used for the comparison. If charging is detected, electron dose is adjusted, typically just in specimen areas associated with charging. Dose is conveniently adjusted by adjusting electron beam dwell time. Upon adjustment, a final image is obtained, with charging effects eliminated or reduced.

Claim (Index 27):
An electron or ion beam imaging system, comprising:\n a scannable electron or ion beam source that produces a scanned electron beam or a scanned ion beam, respectively; a charged particle detector situated to receive charged particles from a specimen in response to irradiation of the specimen with the scanned electron beam or the scanned ion beam; a controller configured to:\n scan the scannable electron beam or ion beam to obtain and store at least a first test image and a second test image based on the charged particles received by the charged particle detector in response to irradiation of the specimen with an initial dose, \n process the first and second test images to identify charging areas on the specimen, \n adjust dose associated with at least one identified charging area, and \n scan the scannable electron beam or ion beam to obtain an image based on the charged particles received by the charged particle detector in response to irradiation of the specimen with the adjusted dose in the identified charging areas.
