CMOS IMAGE SENSOR WITH IMPROVED FILL-FACTOR AND REDUCED DARK CURRENT

摘要

A photosensor and an imaging array utilizing the same are disclosed. The photosensor[150] includes a light conversion region[151] that has separate charge storage regions [172-174]. The light conversion region includes a plurality of separate charge storage regions [172-174] within a doped region[151], each charge collection region being doped such that the mobile charges generated by light striking that charge storage region are prevented from moving to an adjacent charge storage region. The photosensor also includes a plurality of transfer gates[152, 153, 154], having a gate region adjacent to a corresponding one of the charge storage regions and disposed between that charge storage region and a drain region[162-164]. The charge collection regions and the drain regions are doped such that the mobile charges collected in the charge storage region will flow to the drain region when a first electric field is applied to the gate region.
