  • Photodiode with a dark current suppression junction
    Patent number: 9768340
    Abstract: This invention relates to field photodiodes based on PN junctions that suffer from dark current leakage. An NBL is added to prove a second PN junction with the anode. The second PN junction is reversed biased in order to remove dark current leakage. The present solution requires no additional masks or thin films steps relative to a conventional CMOS process flow.
    Type: Grant
