Particle beam systems and methods

摘要

An inspection method comprises focusing a particle beam onto a sample; operating at least one detector located close to the sample; assigning detection signals generated by the at least one detector to different intensity intervals; determining, based on the detection signals assigned to the intensity intervals, at least one first signal component related to electrons incident on the detector; and determining, based on the detection signals assigned to the intensity intervals, at least one second signal component related to X-rays incident on the detector.
