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 15):
A method for controlling dispersion in a charged particle beam system with a beam separator, comprising:\n providing a source conversion unit to form a plurality of images of a source by a plurality of beamlets of a primary charged particle beam generated by the source; providing a first dispersion device in paths of the plurality of beamlets; placing the first dispersion device upstream of the beam separator; generating a plurality of first primary beam dispersions to the plurality of beamlets by the first dispersion device; and adjusting the plurality of first primary beam dispersions to cancel impacts of a plurality of second primary beam dispersions generated by the beam separator to the plurality of beamlets,\n wherein the first dispersion device comprises a first electrostatic deflector and a first magnetic deflector respectively exerting a first force and a second force on each of the plurality of beamlets, the first force and the second force are opposite to each other and form the corresponding first primary beam dispersion.
