FIB low acceleration processing

FIB: Focused Ion Beam Processing

In the method for preparing thin film samples for TEM observation using FIB, high-energy Ga ions (acceleration voltage of 30 kV) are used, resulting in the formation of a damage layer on the processed surface, which causes a deterioration in the image quality of the TEM. By performing processing at a lower acceleration (2 kV) than conventional methods, the damage layer can be reduced, leading to improved image quality. By reducing the damage on the FIB processed surface through low-acceleration FIB processing, high-quality and reliable data can be obtained in TEM image observation and EELS measurements.
