More Information
Summary:An optical sensor device comprising a conversion region to convert an electromagnetic signal into photo-generated charge carriers is shown. The optical sensor device comprises a read-out node configured to read-out the photo-generated charge carriers and a control electrode which is separated by an isolating material from the conversion region. Furthermore, the optical sensor device comprises a doping region in the semiconductor substrate between the control electrode and the conversion region, wherein the doping region comprises a higher doping concentration compared to a minimum doping concentration of the conversion region, wherein the doping concentration is at least 1000 times higher than the minimum doping concentration of the conversion region and wherein the doping region extends into the semiconductor substrate. Moreover, a projection of the control electrode towards the conversion region overlaps the doping region or is located in the doping region. Embodiments show the optical sensor device as a ti
