eng Abstract:
Direct observation of doped patterns in semiconductor, usually on cleavedsections through multilayers but recently also in plan views of patterneddoping of a technological layer, is acquiring high interest because of its straightforward application in the semiconductor technology. Plenty of experimental data has been collected [1-4] from conventional SEM observation and recently first results showed improved contrasts attainable with specimen immersed into electric field. Main features are the sign of contrast- the p-type regions are always brighter than the n-type ones, and the contrast grows toward lower energies.
