SIMS järjestelmät ja laitteet

Secondary ion mass spectrometry, eli SIMS, on mittausmenetelmä pintojen ja ohutkalvojen kemiallisen rakenteen määrittämiseen. SIMS:ssä näytteen pintaan kohdistetaan ionisuihku ja pinnasta irtoavat atomit, molekyylit sekä molekyyliryppäät analysoidaan massaspektrometrisesti. SIMS-tekniikoita voidaan käyttää koko jaksollisen järjestelmän alkuaineiden karakterisointiin, sekä kvalitatiivisesti että kvantitatiivisesti. SIMS sopii sekä alkuainekuvantamiseen, että syvyysprofilointiin kiinteistä näytteistä.

SIMS-tekniikka jaetaan kahteen alakategoriaan, staattiseen (static SIMS) ja dynaamiseen (dynamic SIMS tai DSIMS). Staattinen SIMS keskittyy yleensä ylimpään tai muutamaan ylimpään molekyylikerrokseen ja niiden atomi- sekä molekyylirakenteeseen.

Dynaamisessa SIMS:ssä voimakkaampi ionisäde kohdistetaan näytteeseen pidemmän aikaa, jolloin ionisäteen ionit (happi tai cesium) sekoittuvat näytteeseen, mikä lopulta saavuttaa vakaan tilan. Tätä tekniikkaa käytetään erityisesti puolijohteiden faasirajapintojen ja atomilisäysten (doping) sekä kontaminaatioiden tunnistamiseen.

Hiden Analytical valmistaa SIMS-laitteistoja sekä kvadropoli-detektoreilla, että time-of-flight (ToF)-detektorilla. Lisäksi he valmistavat erilliskomponentteina ionikanuunoita ja massadetektoreita SIMS-käyttöön kustomointeihin, SEM lisälaitteiksi ja muihin vastaaviin tarkoituksiin. Hiden Analyticalilta löytyy monipuolisesti eri tason SIMS-laitteistoja eri käyttötarkoituksiin.

The ion gun geometry is optimised to be ideal for nanometre depth resolution and near surface analysis.

A rotary carousel enables 10 samples to be simultaneously loaded for measurement into the dry-pumped vacuum chamber. The instrument has a small footprint and is exceptionally easy to use, it boasts the same control software and ion gun system as the fully featured Hiden SIMS Workstation family, providing depth profiles, 3D and 2D images and mass spectral data. The MAXIM-600P detector is based around the highly reliable Hiden 6mm triple quadrupole mass filter with pulse ion detection. An electron gun option is available for analysis of insulating samples.

In addition to SIMS, the Compact SIMS has an SNMS facility that is useful for quantification of high concentration elements, such as alloys.

HIDEN UHV ohutkalvojen pintojen syvyyden profiloija

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

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).

Hiden Analytical’s SIMS Workstation

Our SIMS workstation is a comprehensive solution for depth profiling and compositional analysis of samples in various areas of surface analysis, thin film engineering, nanotechnology, fuel cell research, and more. The system is highly customizable to suit the unique requirements of users in complex fields.

XPS SIMS workstation
UHV surface science system option providing for XPS, UPS, AES, SAM, ISS and LEIS

A multi-technique UHV surface science system option providing for XPS, UPS, AES, SAM, ISS and LEIS installed on the Hiden SIMS Workstation

X-ray Photoelectron Spectroscopy is a highly complementary technique providing atomic composition and chemical state bonding information. XPS can be used to quantify high concentrations and is thus ideal for providing calibration points for the very much more sensitive SIMS technique. 

The Hiden SIMS Workstation two-part chamber is designed specifically to mount the XPS upgrade using state-of-the-art components from SPECS® and togther with tilting sample holders allowing for both XPS and SIMS techniques on the same UHV platform without compromise.

The PHOIBOS 150 HV analyzer series is the intrument of choice for high energy XPS analysis (HAXPES). High voltage power supplies and a  highly stable analyzer design allow photoemission up to a kinectic energy of 7 keV, covering most of the existing X-ray light sources and synchrotron facilities.

This analyzer can be operated in high voltage mode and in additon in all relevant analysis modes, such as (M)XPS, UPS, as well as AES, ISS and LEISS. Its design and the modular supplementary hardware makes this analyzer the most versatile PES analyzer in the market. It can easily be upgraded with all available SPECS detection systems.

The integrated 1D-DLD detector is the best performing detection system available. The direct detection of electron signals yield quantitative counts per second (cps). The powerful electronics can aquire ultrafast snapshot measurements of the energy spectrum with up to 1200 energy channels as well as continous sweeping energy spectra. Its low dark count rate and high linearity make this detector outstanding for XPS analyis.

The analyzer comes with a highly stable power supply, the HSA 7000, for best performance in at high and medium kinetic energy range up to 7000 eV.
