Abstract
The characteristics of Dark Current Random Telegraph Signal (DC-RTS), observed in Pinned PhotoDiode (PPD) CMOS Image Sensors (CIS), are investigated thanks to a dedicated analysis tool. Our results demonstrate, for the first time in PPD CIS, that this DC-RTS is due to meta-stable oxide interface SRH generation centers located in the transfer gate depletion region.
