Charged particle beam column and method of operating same
Abstract:
A charged particle beam column includes a charged particle beam source to generate a charged particle beam; an objective lens to focus the charged particle beam in an object plane; a first condenser lens disposed in a beam path of the charged particle beam between the charged particle beam source and the objective lens; a deflector disposed in the beam path between the first condenser lens and the objective lens and configured to change an angle of incidence of the charged particle beam in an object plane; and an aberration corrector disposed in the beam path between the deflector and the objective lens and configured to compensate aberrations introduced by the objective lens. The aberration corrector is also configured to not compensate aberrations introduced by the first condenser lens.
