发明名称 METHOD AND DEVICE FOR ALIGNING A CHARGED PARTICLE BEAM COLUMN
摘要 The invention provides a method for automatically aligning a beam of charged particles with an aperture. Thereby, a defocusing is introduced and a signal calculated based on an image shift is applied to a deflection unit. Further, a method for correction of astigmatism is provided. Thereby, the sharpness is evaluated for a set of frames generated whilst varying the signals to a stigmator.
