Abstract
A multi-beam electronics scanning system using swathing. The system includes an electron emitter source configured to emit an illumination beam. The illumination beam is split into multiple electron beams by a beam splitter lens array. The system also includes an electronic deflection system configured to deflect each of the electron beams in a plurality of directions, including a first direction, along two different axes. Last, a swathing stage is used to move a sample with a constant velocity in a second direction that is parallel to the first direction.
