SUPPRESSION OF DARK CURRENT IN A PHOTOSENSOR FOR IMAGING
摘要:
A pixel cell having a halogen-rich region localized between an oxide isolation region and a photosensor. The halogen-rich region prevents leakage from the isolation-region into the photosensor, thereby suppressing dark current in imagers.
