SEM's at DTU Danchip:


Equipment performance and process related parameters

Equipment SEM Supra 3 (Supra 40VP SEM)
Purpose Imaging and measurement of
  • Any sample except bulk insulators such as polymers, glass or quartz wafers
Location
  • Cleanroom of DTU Danchip
Performance Resolution
  • 1-2 nm (limited by vibrations)

The resolution is strongly dependent on the type of sample and the skills of the operator.

Instrument specifics Detectors
  • Secondary electron (Se2)
  • Inlens secondary electron (Inlens)
  • High Definition four quadrant Angular Selective Backscattered electron detector (HDAsB)
  • Variable pressure secondary electron (VPSE)
Stage
  • X, Y: 130 × 130 mm
  • T: -4 to 70o
  • R: 360o
  • Z: 50 mm
Electron source
  • FEG (Field Emission Gun) source
Operating pressures
  • Fixed at High vacuum (2 × 10-4mbar - 10-6mbar)
  • Variable at Low vacuum (0.1 mbar - 2 mbar)
Options
  • High Definition four quadrant Angular Selective Backscattered electron detector (HDAsB)
Substrates Batch size
  • Up to 6" wafer with full view
Allowed materials
  • Any standard cleanroom material
