  • Patent number: 6812462
    Abstract: Method and apparatus for imaging at multiple perspectives of a specimen are disclosed. In one embodiment, an apparatus for generating a multi-perspective image using multiple charged particle beams (e.g., electron beams) is disclosed. In one embodiment, the apparatus generally includes a charged particle beam generator system arranged to generate and control a first charged particle beam directed substantially at a first angle towards the specimen and a second charged particle beam directed substantially at a second angle towards the specimen. The apparatus also includes an image generator arranged to generate one or more images based on charged particles emitted from the specimen in response to the first and second charged particle beams and a controller arranged to cause the charged particle beam generator to direct both the first charged particle beam and the second charged particle beam at a first area of the specimen.
