Secondary Ion Mass Spectroscopy ION-TOF TOF.SIMS5 (SIMS)

Profile card (PDF)

TOF-SIMS is an acronym for the combination of the analytical technique SIMS (Secondary Ion Mass Spectrometry) with Time-of-Flight mass analysis (TOF). The technique provides detailed elemental and molecular information about the surface, thin layers, interfaces of the sample, and gives a full three-dimensional analysis.
For a TOF-SIMS analysis, a solid surface is bombarded by primary ions of some keV energy. The primary ion energy is transferred to target atoms via atomic collisions and a so-called collision cascade is generated. Part of the energy is transported back to the surface allowing surface atoms and molecular compounds to overcome the surface binding energy. The interaction of the collision cascade with surface molecules is soft enough to allow even large and non-volatile molecules with masses up to 10,000 u to escape without or with little fragmentation.
 
Sputtering is achieved by a sputter beam of reactive species (O2 or Cs) at low energy for increased sensitivity, high depth resolution, and short transients. Analysis is performed by a short pulse length and small spot size ion beam for high mass and lateral resolution. By digitally scanning the bismuth analysis beam, high spatial resolution ion images of all secondary ions from the sample surface are produced. By sputtering the sample surface simultaneously by cesium or oxygen beam, images from increasing depth are obtained and hence three dimensional data are collected.

The TOF.SIMS 5 is the latest generation of high-end TOF-SIMS instruments developed by IONTOF Company. Its design guarantees optimum performance in all fields of SIMS applications. The instruments offers three ion sources offering Bi1–7+, Cs+ and O2+ and is equipped with a reflectron TOF analyzer giving high secondary ion transmission with high mass resolution (up to 11,000), a sample chamber with a 5-axis manipulator (x, y, z, rotation and tilt) for flexible navigation, charge compensation for the analysis of insulators, a secondary electron detector for SEM imaging. Samples can be heated and cooled if analysis of volatiles is needed (-130°C to + 600°C with a precision of +/- 1°C).
In a TOF-SIMS experiment the primary ion beam is pulsed to get good mass resolution. Consequently the current density and also the resulting erosion speed is very low (< 0.1nm/min). Therefore, depth profiling and 3D analysis with a TOF-SIMS instrument is done in the so-called dual beam mode. While the first beam (Cs+ or O2+) is sputtering a crater, the second beam (Bi1–7+ ) is progressively analyzing the crater bottom.
The key advantage of the dual beam mode is the possibility to adjust the analysis and the sputter parameter independ
