Abstract:
Systems and methods are provided for compensating dispersion of a beam separator in a single-beam or multi-beam apparatus. Embodiments of the present disclosure provide a dispersion device comprising an electrostatic deflector and a magnetic deflector configured to induce a beam dispersion set to cancel the dispersion generated by the beam separator. The combination of the electrostatic deflector and the magnetic deflector can be used to keep the deflection angle due to the dispersion device unchanged when the induced beam dispersion is changed to compensate for a change in the dispersion generated by the beam separator. In some embodiments, the deflection angle due to the dispersion device can be controlled to be zero and there is no change in primary beam axis due to the dispersion device.

Claim (Index 14):
The charged particle beam system of  claim 1 , further comprising a second dispersion device which is between the beam separator and the detection device and generates a plurality of first secondary beam dispersions to the plurality of secondary charged particle beams, the second dispersion device comprising:\n a third electrostatic deflector and a third magnetic deflector, respectively exerting a third force and a fourth force on each of the plurality of secondary charged particle beams, the third force and the fourth force are opposite to each other and form the corresponding first secondary beam dispersion,\n wherein the plurality of first secondary beam dispersions is adjusted to cancel impacts of a plurality of second secondary beam dispersions generated by the beam separator to the plurality of secondary probe spots.
