Electron Microscopy and Analysis Facility

The Electron Microscopy and Analysis Facility (EMAF) delivers state-of-the-art electron microscopy analyses with rapid turnaround time for industry and academia

Electron Microscopy

We develop customer- and product-specific analysis of materials and devices and provide comprehensive understanding of the measurement results:

  • Product contamination analysis
  • Thin film analysis (thickness + structure)
  • Failure analysis
  • Materials characterisation
  • Surface analysis
  • (S)TEM sample preparation
  • Trace analysis >10ppm
  • 3D visualisation
  • Correlative microscopy
  • Focused ion beam (FIB) patterning/prototyping.

Methods

  • Scanning electron microscopy (SEM) 
  • Elemental analysis (EDX and ToF-SIMS) 
  • (Scanning) transmission electron microscopy (S)TEM 
  • Dual beam focused ion beam (FIB) 
  • Electron Backscatter Diffraction (EBSD) 
  • Electron diffraction (SAED) 
  • Electron column for UHR imaging (immersion lens for non-magnetic samples only) 
  • Analysis mode: SE detector, for topography contrast 
  • UHR-resolution mode: In-beam SE 
  • Backscattered Mode: In-Beam f-BSE, Mid angle BSE 
  • Retractable BSE detector, for wide angle backscattered electrons for material contrast 
  • Retractable HADF STEM (R-STEM) detector: Bright field, Dark field and High Angle Dark Field 
  • SEM Resolution
    • 0.6nm @30kV, 20kV, and 15kV
    • 0.7nm @10kV
    • 1.0nm @5kV
    • 1.2nm @1kV
    • 1.7nm @500V
