Large-area optical sensors

Turn to imec for the development of new photodetectors, design of readout backplanes and integration of the two to enable large-area sensing applications.

Arrays of photosensitive pixels distributed over large areas are crucial for important applications such as:

  • x-ray detectors (radiology, mammography)
  • fingerprint scanners (biometrics)
  • curved imagers (inspection)

Such arrays are constituted of two components:

  1. The thin-film photodetector (TFPD) frontplane ensures the selection of the most appropriate sensor, with organic, quantum dot and perovskite absorbers to choose from.
  2. The thin-film transistor (TFT) backplane enables large sensing areas, flexibility and even transparency, with the manufacturing process compatible with flat-panel display (FPD) industry.

Thin-film image sensor films developed by imec and Holst Centre for detecting fingerprints and palm prints.

Imec specializes in the development of new photodetectors, design of readout backplanes and integration of the two.

Over the years, we have demonstrated proof-of-concept devices showing different modalities of large-area image sensors.
