    Abstract: A multi-column scanning electron microscopy (SEM) system is disclosed. The SEM system includes a source assembly. The source assembly includes two or more electron beam sources configured to generate a plurality of electron beams. The source assembly also includes two or more sets of positioners configured to actuate the two or more electron beam sources. The SEM system also includes a column assembly. The column assembly includes a plurality of substrate arrays. The column assembly also includes two or more electron-optical columns formed by a set of column electron-optical elements bonded to the plurality of substrate arrays. The SEM system also includes a stage configured to secure a sample that at least one of emits or scatters electrons in response to the plurality of electron beams directed by the two or more electron-optical columns to the sample.

    Abstract: A multi-column scanning electron microscopy (SEM) system includes a column assembly, where the column assembly includes a first substrate array assembly and at least a second substrate array assembly. The system also includes a source assembly, the source assembly including two or more illumination sources configured to generate two or more electron beams and two or more sets of a plurality of positioners configured to adjust a position of a particular illumination source of the two or more illumination sources in a plurality of directions. The system also includes a stage configured to secure a sample, where the column assembly directs at least a portion of the two or more electron beams onto a portion of the sample.
