摘要:
Multi-beam scanning electron microscope (SEM) inspection systems with dark field imaging capabilities are disclosed. An SEM inspection system may include an electron source and at least one optical device. The at least one optical device may be configured to produce a plurality of primary beamlets utilizing electrons provided by the electron source and deliver the plurality of primary beamlets toward a target. The apparatus may also include an array of detectors configured to receive a plurality of image beamlets emitted by the target in response to the plurality of primary beamlets and produce at least one dark field image of the target.
