Abstract
An electron beam microscope includes an electron beam pattern source, a vacuum enclosure, electron optics, a detector and a processor. The electron beam pattern source generates a sequence of electron beam patterns for illuminating a set of pixels on a specimen. The electron optics directs the sequence of electron beam patterns to the specimen. The detector detects a result of an interaction between each of the electron beam patterns and the specimen and produces a sequence of detector signals. The processor, in response to the sequence of detector signals, generates an image including a pixel value representative of each of the illuminated of pixels on the specimen. The electron beam microscope preferably includes a deflector for deflecting each of the electron beam patterns relative to the specimen.
