Detectors for ionizing radiation

Atomic particles with sufficient kinetic energy and X-rays can be detected directly via their absorption on the crystal lattice or indirectly via scintillators with silicon radiation detectors. This can require very high absorption volumes and extremely low dark currents, in some cases with fully depleted wafers. First Sensor offers solutions for energy-dispersive spectroscopy.

Special features

  • Wafer thickness up to 700 µm
  • Very low dark current signals
  • Very low capacitance levels
  • Minimal series resistance at full depletion
