ABSTRACT:
A charged particle beam device including a function for measuring localized static charges on a sample. A primary charged particle beam scans a sample positioned in a mirror state to acquire an image. The acquired image may be an image of the sample or may be an image of a structural component in the charged particle optical system. The acquired image is compared with a standard sample image and the localized static charge is measured.
