/Thin-film image sensors

Thin-film image sensors


Imec develops disruptive technologies for image sensors based on thin-film photodetectors. Ultra-thin, submicron active layers with absorption coefficients much higher than those of silicon and other materials, thus enabling new form factors and applications. 

Our solution

Imec is active in the full value chain, from screening new promising materials through pixel development all the way to image sensor prototyping and technology transfer to industrial fabs. 

We integrate thin-film photodetectors with thin-film transistor (TFT) backplanes to develop large-area, flexible sensors that can be used for medical or industrial x-ray imaging or for conformable, curved focal planes. 

We also integrate thin-film photodetectors with CMOS readout chips to develop monolithic infrared image sensors with high resolution. 

Available and developing IP blocks

  • Thin-film photodetector stack based on polymers, small molecules, metal oxides, perovskites and quantum dots
  • Design and fabrication technology for TFT-based readout backplanes (passive and active pixel)
  • Integration technology for TFPD on TFT and on CMO


  • medical x-ray
  • non-destructive testing / sorting
  • gesture recognition
  • biometric / fingerprint
  • security and surveillance
  • free-form imaging surface
