Conductive Coating
是涂导电涂料那一步吧,下面是英文的Wiki百科.找的好苦啊.
Conductive Coating – An ultrathin coating of electrically-conducting material,deposited either by high vacuum evaporation or by low vacuum sputter coating of the sample.This is done to prevent the accumulation of static electric fields at the specimen due to the electron irradiation required during imaging.Such coatings include gold,gold/palladium,platinum,tungsten,graphite etc.and are especially important for the study of specimens with the scanning electron microscope.Another reason for coating,even when there is more than enough conductivity,is to improve contrast,a situation more common with the operation of a FESEM (field emission SEM).When an osmium coater is used,a layer far thinner than would be possible with any of the previously mentioned sputtered coatings is possible.[12]
