The IMO-IMOMEC Organic and biopolymer chemistry group (OBPC-group) develops new technologies for monolitic image sensors for the near infrared wavelength range.

This project aims to produce these sensors to increase the resolution with a cheaper production process, by using new organic thin film photo active materials, integrated in a CMOS readout unit. On the one hand this provides a wider spectrum compared to standard silicon-based image sensors. The deposition and integration of a thin film photo-detecting layer on the other hand makes it possible to develop a monolithic image sensor.

The result is a cost saving by about a factor of 10 compared to current hybrid NIR imaging sensors in which an InGaAs image sensor is read-out circuit is integrated on a CMOS. The monolithic approach gives a much higher image resolution (with a pixel pitch of 5 micrometers) compared with the current hybrid solutions.
