TheChallenge
Thin-film photodiode (TFPD) devices based on active materials,such as quantum dots, organic layers and perovskites, are constantly beingdeveloped and improved at imec to enable novel sensing capabilities beyondconventional silicon technology.
The active material properties are characterized by theprocess engineers who develop the photodiode structure in the lab and evaluatedevice performance on large, millimeter-sized single contacts. However, imagesensors contain hundreds of thousands of micrometer-scale pixels that operateunder conditions very different from laboratory test structures. As a result,processing-lab measurements do not translate directly to image sensors, wheredifferent properties matter and different characterization methods arerequired. Moreover, since the characterization can take a long time, it isimportant to automate the measurements where possible.
In this project we aim to expand the suite ofcharacterizations that are available to evaluate the performance of the imagesensors. We will develop procedures for image lag, blooming and MTF. Othermetrics could be included depending on the progress of the student.
