Evolution and revolution in SIMS
Ian Gilmore
NPL London, United Kingdom
Since its beginnings, SIMS has evolved along distinct paths depending on the application. The relentless progress of Moore’s law drove innovation in high-sensitivity mass spectrometers with atomic scale depth resolution and formed the “depth profiling” community. The requirements for organic and later biological applications were quite different driving innovation in imaging, reduced damage and the emission and detection of larger molecules giving rise to the “static SIMS” community. Tremendous progress was made in both evolutionary lines but was compartmentalised.
The last decade has brought revolutions in the ion beam technology and mass spectrometers that have brought a convergence to the field. For example, gas cluster ion beams enable molecular depth profiling with high-depth resolution and imaging with < 1 µm resolution. Innovation in mass spectrometers e.g. J105 (Ionoptika, UK) and OrbiSIMS (IONTOF, Germany) now bring the ability for high-duty cycle (sensitivity) that matches the performance on magnetic sector instruments used for semiconductor profiling but also with high-mass resolution and MS/MS capabilities for improved identification. Examples of these revolutions and convergence in the field will be provided.
The next decade will see further advances in mass spectrometers, for example multiple reflection ToF (Waters, UK) and hybrid analysers (e.g. Orbitrap-ASTRAL, Thermo) and improved sensitivity using quantum detection.
