Expertises

High Resolution Microscopy

High resolution microscopy with unequaled depth of focus. Imaging of insulating substrate without any conducive layer deposition thanks to the electron neutralizer

High resolution lithography

The very small spot size and the quasi absence of proximity effect allow to obtain high very small features and high density

High resolution direct milling

High resolution milling with a low yield with He ions. Yield can be improved using Neon ions to the detriment of weaker resolution. Unlike using Gallium ion milling there is no contamination of residual ions

High resolution growth

The Oxford OMNIGIS system offers three gas precursors to deposit tungsten, platinum and SiO. Due to the exeptional depth of focus of the ion column and the fine spot together with a small interaction volume of the ions it possible to grow high aspect ratio nanowires

Nano-manipulation

With the help of the two IMINA robots moving inside on the stage specimen holder, it is possible to either measure in situ the electrical characteristics of a nanostructure or manipulate them
