Method and device for the automatic generation of images adapted to align a charged particle beam column |
摘要 |
<p>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.</p> |
