A UHV surface analysis system for thin film depth profiling
Hiden Analytical provides extremely versatile high-sensitivity instrumentation for high performance dynamic and static SIMS (secondary ion mass spectrometry) analysis, unlocking new levels of precision in cutting-edge applications. With an extended range and the ability to acquire and identify both positive (+ve) and negative (-ve) secondary ions, the SIMS workstation is a comprehensive solution for composition analysis and depth profiling applications.
For simultaneous +ve and -ve ion analysis in a comprehensive SIMS package, Hiden Analytical has also developed the innovative Hi5 SIMS workstation. Find more information in our product literature below.
This technique is broken down into two distinct methodologies: dynamic and static SIMS. Each of these uses a primary ion beam that impacts a sample in vacuum conditions, causing extremely small volumes of material to be ablated from the surface – a fraction of this ejected material will be ionised. These secondary ions are acquired by the sample inlet of the mass spectrometry unit to develop a robust understanding of the composition of the specimen’s uppermost surface layers.
The primary difference between dynamic and static SIMS is the ion dosage (a higher dose for dynamic SIMS instruments), and that dynamic SIMS cannot be run with a defocussed ion beam; it must be raster scanned across the sample surface to produce a flat-bottomed crater. Hiden Analytical’s SIMS workstation can perform both dynamic and static SIMS analysis in a single consolidated SIMS instrument. With a dual-mode MAXIM mass spectrometer, the SIMS workstation can operate in secondary ion detection mode for +ve/-ve ion detection, and in a secondary neutral detection mode for +ve data quantification. Each mode is compatible with mass range options up to 5000 atomic mass units (amu).

The SIMS Mapper software provides a simple, but powerful, user interface to the SIMS tool. The species to be analysed are chosen from a period table view, with mass interferences highlighted, and the data are collected as images throughout the analysis. For depth profiles the gated area can be defined after analysis and images may be stacked to reconstruct the concentration profile in three dimensions. For less experienced operators, or in a production environment, analyses can be run from previously stored templates and fully automated “queued” running is possible with the automatic stage option. A range of data export formats allows results to be used by other software packages for enhanced display or processing.
