Efficiency of Collection of the Secondary Electrons in SEM.

Popis výsledku v původním jazyce

Great effort has been invested into upgrading the image resolution in SEM up to some 1nm at 15 keV. However, uncertainty still exists as regards proper appearance of even standard testing specimens. The same energy, current and impact angle of the primary beam and the same type of the secondary electron (SE) detector do not secure identical image contrast. Many details regarding generation, collection and detection of the signal species are important and a quantitative method of the detector assessmentis needed. Magnetic and electrostatic fields in the specimen vicinity surely influence the SE trajectories toward detector and these fields vary with the working distance, with arrangement of grounded metallic parts in the specimen chamber, etc. The recently opened systematic study of this problem was started by examination of the collection efficiency.
