Ya. Novikov et al., DETERMINATION OF THE DIAMETER OF THE ELECTRON-PROBE OF A SCANNING ELECTRON-MICROSCOPE, Measurement techniques, 36(12), 1993, pp. 1348-1350
A technique is proposed for determining the diameter of electron probe
s used in modem scanning electron microscopes within 1-nm error limits
by means of a linear gauge. The gauge is designed for the calibration
of such microprobes and represents a relief structure in the form of
slotted grooves in silicon with a nearly rectangular profile.
