Backside illuminated photodiode arrays


Backside illuminated (BSI) photodiode technology enables manufacturing of fully tileable photodiode array modules meeting all the requirements of modern multislice and true volumetric CT scanners. BSI photodiode array solutions are tailored to interface to customer detector mechanics and data acquisition systems.

A well proven and optimized manufacturing and supply chain ensures cost effective and high quality sensor solutions. Detection Technology’s BSI technology can be used for medical, industrial and security applications.

  • Fully tileable modules enable building of very large detectors
  • BSI chip(s) mounted on rigid substrates with finest precision
  • Photodiode geometry can be customized to any shape and dimension based on customer requirements
  • Excellent responsivity based on an optimized photodiode process and antireflective layer
  • Module interconnection to the readout system by flex-cable or connector
  • N type silicon substrate with P type anodes on the non-illuminated side of the chip
  • Flip chip assembly technology utilized for the internal interconnections
