Low noise thin-film pixel design for high performance CMOS image senor (CIS)

PhD - Leuven | More than two weeks ago

Lowest noise image sensor pixel design using ‘Foreign material’! 


Image sensors are now everywhere. Continued development over the past decades has perfectioned image sensor technology and state-of-the-art imagers are reaching the theoretical limit of classical photography. At the same time, thin-film materials, such as organic, quantum-dot, perovskite, etc., are being researched as alternative photodetector thanks to numerous advantages such as higher absorption coefficient, different bandwidth and infrared detection capability, to name a few. However, image sensors based on these foreign materials have never seen wide deployment because of comparably higher noise than silicon CIS.  



The goal of this PhD is to develop thin-film-based pixel devices and technologies to advance next generation consumer image sensors.  This research topic encompasses topics from quantum mechanical effects to solid state physics through circuit design and digital photography. To do so, literature study will be a first step to investigate different device concepts, explore their limits and potential and identify promising new avenues.  Following steps will be the design and validation of these new devices using TCAD, layout of test structures, implementation of the device into imec imager platforms in collaboration with our technology experts, development of the required measurement techniques and the characterization of the fabricated devices.
