Sub-5 nm FIB direct patterning of nanodevices

Nanoengraving of membranes as a template for nanopores fabrication is an application field of growing interest. Similarly to the formation of ion tracks in membranes created when high-energetic ions pass trough thin foils, it is possible with a FIB system to fabricate, design and organise nanodevices within thin membranes. In this work, we detail the advanced methodology we have carefully optimised for such deep sub-10 nm nanodevices fabrication using our high-performance FIB instrument.
