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.

Applications

Overview

Secondary ion mass spectrometry, or SIMS, is one of the most sensitive techniques ever developed for interrogating the uppermost surface layers of a material, from depths of several hundred nanometres (nm) to a single atomic layer. It can obtain compositional data down to the parts per billion (ppb) range and is compatible with any material that can reliably be tested in vacuum conditions. Consequently, SIMS instruments are routinely used to analyse ceramics, metals, organic materials, polymers, semiconductors, and more.

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).
