Fully automatic FIB/SEM tomography
fabrication | news

The nanoFAB is pleased to announce that the FIB/SEM tomography is fully commissioned on the Helios Hydra Plasma FIB/SEM dual beam system

FIB/SEM tomography is a high-resolution 3D volume analysis technique, by serial sectioning – sequential application of SEM imaging and FIB milling.

Process details:
Volume 1: O beam, 30 kV, 1.7 nA, 3 nm slice thickness, 4550 slices
Volume 2: Xe beam, 30 kV, 4 nA, 5 nm slice thickness, 5990 slices

Multiple ion species (Xe, Ar, O, or N) are available, enabling optimal ion beams for various types of materials. While Xe beam is suitable for general inorganic materials, Oxygen ions provide much better milling quality for biological samples embedded in resins, in terms of less milling artifacts.

The ASV FIB/SEM tomography process is now available to users as staff analysis. If you have needs for these analysis, please submit a “sample” request with sample details on LMACS. If you have any questions, please feel free to contact Peng Li (Peng.Li@ualberta.ca) – the Characterization Group Manager.
