SACP method and particle optical system for performing the method
Abstract:
An SACP method includes directing a beam of charged particles onto an object surface of an object using a particle optical system, and detecting intensities of particles emanating from the object. The method further includes: (a1) adjusting an excitation of the second beam deflector for adjusting an impingement location of the beam on the object surface; (a2) adjusting an excitation of the first beam deflector for adjusting an angle of incidence of the beam on the object surface without changing the impingement location and detecting the intensity; and (a3) repeating the adjusting of the excitation of the first beam deflector for adjusting the angle of incidence without changing the impingement location such that a corresponding intensity is detected for each of at least 100 different angles of incidence at the same impingement location.
