Techniques and Applications:
FIB Helios 600i is capable of fabricate structures with feature size down to 10 nm by both low current etching and GIS assisted deposition, in the construction of micro-/nano electronic devices, optic-electronic devices, bio-sensors/channels, MEMS/NEMS, superconducting/magnetic devices, photonic crystals, plasmonic devices and so on, as well as to explore the novel physic phenomena and effects in nanometer scale. It can also be used to fabricate TEM cross-section for atomic scale analysis, with much increased material removal speed as well as much reduced damages and contaminations using the very low current polishing and imaging. In addition, the system is equipped with nano-manipulators for in-situ object transfer.
