Microscope overview

The FIB/SEM has been installed in CLYM at the beginning of 2010. It’s an NVision 40 from Zeiss which is composed of an electronic column Gemini I and of an ionic column SIINT Zeta Ga+. The ionic column allows the sputtering of matter with a nano-metric precision. Thus it is possible to modify or create samples with particular shapes or to observe under the surface. The FIB/SEM possesses several equipment as :

  • A gas injection system: possibility to do in situ deposition of Carbone, Tungstène or SiOx, but also to assist some milling with XeF2 or H2O.
  • 2 micromanipulators : to extract parts of samples
  • A 6 axis sample holder: to do all wanted movements (X, Y, Z, rotation, tilt) and to set the eucentric height of the sample (M).

The CLYM FIB/SEM is also equipped with numerous detectors :

  • In-lens SE and BSE (annular scintillators – good performance at low tension)
  • ET-SE and Secondary Ion detector
  • QBSE (semi-conductor)
  • STEM (0.8 nm@30 kV, Bright field & dark field)
  • EBSD with a NordlysF+ camera(Oxford Instruments, High Wycombe, UK)
  • EDX with a X-max 50mm² Silicon Drift Detector (Oxford Instruments, High Wycombe, UK)

The device has been completed by an external scanning system 16 bit (FIBICS incorporated, Ottawa, CA) capable of controlling the electron and ion beam independently or simultaneously. This unit is driven by the NanoPatterning software and Visualisation Engine (NPVE) for complex etching and includes Atlas3D for FIB nanotomographies.

 

In conclusion, this equipment allows to do a great variety of experiments as nano-patterning, thin lamella creation for TEM analysis, realization of tomography...

FIB Nanostructures
Editors: Wang, Zhiming M. (Ed.)

Within the context of a book writing entitled "FIB NANOSTRUCTURES" reporting an exhaustive state of the art of FIB various applications for the creation of nanostructures, an ILM team (CLYM partner) has been solicited for the radaction of a chapter titled  "FIB Design for Nanofluidic Application".  In this context, the authors have demonstrated that the use of the dual beam NVision 40 system present at CLYM gives access to a whole new application domain: the NanoFluidique.
