  • Scanning electron microscope and a method for overlay monitoring
    Patent number: 11646173
    Abstract: A scanning electron microscope and a method for evaluating a sample, the method may include (a) illuminating the sample with a primary electron beam, (b) directing secondary electrons emitted from the sample and propagated above a first scintillator, towards an upper portion of the first scintillator, wherein the first scintillator and a second scintillator are positioned between the sample and a column electrode of the column; wherein the first scintillator is positioned above the second scintillator; (c) detecting the secondary electrons by the first scintillator; (d) directing backscattered electrons emitted from the sample towards a lower portion of the second scintillator; and (e) detecting the backscattered electrons by the second scintillator.
