Manufacturer and model:

ThermoFisher Helios 5 UC.



The Helios 5 is an integrated focused ion beam (FIB) and scanning electron beam, dual functionality in one machine. The ion column provides fast and precise milling, patterning and imaging of the sample's surface. 

The superior low voltage performance of the ion column facilitates to produce a high-quality thin lamella for TEM.

A Multi-Chem system provides an accurate deposition/etching capability of different layers on the sample. By applying a simultaneous operation of the columns, it is possible to slice the sample very gently and to acquite an immediate SEM image of the slice. By repeating these steps, it is possible to reconstruct a 3D model of the specimen.

  • Precursors for MultiChem:

» Carbon Deposition - Gas chemistry solution (Naphthalene) for Ion or Electron beam deposition of Carbon-based material.

» Insulator Deposition II - Gas chemistry (TEOS) solution for in-situ deposition of insulator.

» Insulator Enhanced Etch - Gas chemistry solution (XeF2) for enhanced etching of insulator materials. This gas chemistry is used to selectively remove insulating materials while inhibiting the removal of conducting materials.

» Selective Carbon Mill - Gas chemistry solution for enhanced etching of carbon-based materials such as resist, polycarbonate or diamonds.

» Tungsten Deposition - Gas chemistry solution for Ion or Electron beam deposition of Tungsten-containing material. Tungsten gas chemistry is the preferred metal deposition in case low electrical resistance of the deposited material is required.
