The focused ion beam has become a powerful tool for site-specific 3D imaging of sub-micron features in a sample. In this FIB tomography technique, the sample is sequentially milled using an ion beam perpendicular to the specimen while imaging the newly exposed surface using an electron beam. This so-called, slice and view approach allows larger scale nano-structures to be characterized across the many imaging modes available to an SEM, including secondary electro… depression treatment facilityWebFig. 1. Factors limiting resolution of IBL. A focused ion beam irradiates a resist layer o n a substrate. The three factors limiti ng resolution are (i) spot size of the beam (ii) ion scattering and (iii) secondary electron emission. Reprinted with permission from Winston D. et al., 2009.
