Abstract:
One modified source-conversion unit and one method to reduce the Coulomb Effect in a multi-beam apparatus are proposed. In the modified source-conversion unit, the aberration-compensation function is carried out after the image-forming function has changed each beamlet to be on-axis locally, and therefore avoids undesired aberrations due to the beamlet tilting/shifting. A Coulomb-effect-reduction means with plural Coulomb-effect-reduction openings is placed close to the single electron source of the apparatus and therefore the electrons not in use can be cut off as early as possible.

Claim (Index 2):
A source-conversion unit of an electron source that emits an electron beam,\n the source-conversion unit comprising: a micro-deflector array that facilitates creation of a plurality of images of the electron source, each of the images being associated with a corresponding beamlet of a plurality of beamlets that are derived from the electron beam; and a micro-compensator array that facilitates adding aberration to each of the beamlets.
