Patent Images
1. An apparatus, comprising:
- an electron source;
a beamlet control mechanism configured to produce a plurality of beamlets utilizing electrons provided by the electron source, the beamlet control mechanism further configured to deliver one of the plurality of beamlets toward a target at a time instance; and
a detector configured to produce an image of the target at least partially based on electrons backscattered out of the target.

Abstract
Multi-beam scanning electron microscope inspection systems are disclosed. A multi-beam scanning electron microscope inspection system may include an electron source and a beamlet control mechanism. The beamlet control mechanism may be configured to produce a plurality of beamlets utilizing electrons provided by the electron source and deliver one of the plurality of beamlets toward a target at a time instance. The multi-beam scanning electron microscope inspection system may also include a detector configured to produce an image of the target at least partially based on electrons backscattered out of the target.
