    Abstract: A method for imaging a surface, including scanning a first region of the surface with a primary charged particle beam at a first scan rate so as to generate a first secondary charged particle beam from the first region, and scanning a second region of the surface with the primary charged particle beam at a second scan rate faster than the first scan rate so as to generate a second secondary charged particle beam from the second region. The method also includes receiving the first secondary charged particle beam and the second secondary charged particle beam at a detector configured to generate a signal in response to the beams, and forming an image of the first and the second regions in response to the signal.

    Abstract: An apparatus and method for scanning a pattern. The method includes: (i) directing a charged particle beam such as to interact with the pattern along a first scan path, and (ii) directing a beam such as to interact with the pattern along a second scan path. The pattern changes one of its characteristics as a result of an interaction with the beam. The distance between the first and the second scan paths may be bigger than the diameter of the charged electron beam. Each of the first and second scan paths may include a plurality of consecutive samples and the distance between the first and second scan paths may be bigger than a distance between adjacent samples. The location of scan paths may be changed between measurements and especially between measurement sessions. The charged particle beam may have an ellipsoid cross section.
