Design and performance of a combined secondary ion mass spectrometry-scanning probe microscopy instrument for high sensitivity and high-resolution elemental three-dimensional analysis

State-of-the-art secondary ion mass spectrometry (SIMS) instruments allow producing 3D chemical
mappings with excellent sensitivity and spatial resolution. Several important artifacts however
arise from the fact that SIMS 3D mapping does not take into account the surface topography of
the sample. In order to correct these artifacts, we have integrated a specially developed scanning
probe microscopy (SPM) system into a commercial Cameca NanoSIMS 50 instrument. This new
SPM module, which was designed as a DN200CF flange-mounted bolt-on accessory, includes a new
high-precision sample stage, a scanner with a range of 100 μm in x and y direction, and a dedicated
SPM head which can be operated in the atomic force microscopy (AFM) and Kelvin probe force microscopy
modes. Topographical information gained from AFM measurements taken before, during,
and after SIMS analysis as well as the SIMS data are automatically compiled into an accurate 3D
reconstruction using the software program “SARINA,” which was developed for this first combined
SIMS-SPM instrument. The achievable lateral resolutions are 6 nm in the SPM mode and 45 nm in the
SIMS mode. Elemental 3D images obtained with our integrated SIMS-SPM instrument on Al/Cu and
polystyrene/poly(methyl methacrylate) samples demonstrate the advantages of the combined SIMSSPM
approach.

IRMA-2 at SOLEIL: a set-up for magnetic and coherent scattering of polarized soft x-rays

April 2012

M Sacchi et al 2013 J. Phys.: Conf. Ser. 425 202009

We have designed, built and tested a new instrument for soft x-ray scattering experiments. IRMA-2 is a UHV set-up for elastic and coherent scattering experiments developed at the SEXTANTS beamline of the SOLEIL synchrotron. Applications will be in the field of solid state physics, with emphasis on the investigation of the magnetic properties of artificially structured materials.

Three dimensional imaging using secondary ion mass spectrometry and atomic force microscopy

September 2011

Applied Surface Science

Volume 258, Issue 4, 1 December 2011, Pages 1322–1327

With the breakthroughs in lateral resolution with regards to secondary ion mass spectroscopy in recent years, new areas of research with much promise have opened up to the scientific community. Even though the much improved lateral resolution of 50 nm can effectively deliver more accurate 3D-images, the traditional 3D reconstructions, consisting of compiling previously acquired successive secondary ion mass spectrometry images into a 3D-stack, do not represent the real localized chemical distribution of the sputtered volume. Based on samples initially analyzed on the Cameca NanoSIMS 50 instrument, this paper portrays the advantages of combining the topographical information from atomic force microscopy and the chemical information from secondary ion mass spectrometry. Taking account of the roughness evolution within the analyzed zone, 3D reconstructions become a lot more accurate and allow an easier interpretation of results. On the basis of an Al/Cu sample, a comparison between traditional 3D imaging and corrected 3D reconstructions is given and the advantages of the newly developed 3D imaging method are explained.

WHEN a system is poised at a critical point between two macroscopic phases, it exhibits dynamical structures on all available spatial scales, even though the underlying microscopic interactions tend to have a characteristic length scale. According to the universality hypothesis^1,2, diverse physical systems that share the same essential symmetry properties will exhibit the same physical behaviour close to their critical points^1,3–5; if this is so, even highly idealized models can be used to describe real systems accurately. Here we report experimental confirmation that the scaling behaviour of thermodynamic variables predicted by the universality hypothesis holds over 18 orders of magnitude. We show that the equation of state of a two-dimensional system (an atomic layer of ferromagnetic iron deposited on a non-magnetic substrate) closely follows the behaviour⁶ of the two-dimensional Ising model⁷—the first and most elementary statistical model of a macroscopic system with short-range interactions³.
