In summary, FIB technology has advanced ion beam etching and deposition techniques, enabling precise material modification and fabrication of complex structures.
Focused Ion Beam (FIB) technology offers powerful imaging capabilities that allow researchers to visualize and analyze samples at a high resolution.
FIB can be used for imaging through two main techniques: secondary electron imaging and ion beam-induced secondary electron imaging.
Secondary electron imaging involves detecting the secondary electrons emitted from the sample surface when it is bombarded by the ion beam. This technique provides high-resolution images with excellent topographical contrast, allowing researchers to observe surface features and textures in detail.
Ion beam-induced secondary electron imaging, on the other hand, involves detecting the secondary electrons emitted by the ion beam itself as it interacts with the sample. This technique offers excellent material contrast and enables the visualization of subsurface structures and interfaces.
Both imaging techniques can be combined with other analytical techniques, such as energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD), to obtain comprehensive information about the sample's composition, crystal structure, and elemental distribution.
In summary, FIB technology provides powerful imaging capabilities through secondary electron imaging and ion beam-induced secondary electron imaging, enabling researchers to visualize and analyze samples at a high resolution.
