Abstract:
The present disclosure relates to a CMOS image sensor, and an associated method of formation. In some embodiments, the CMOS image sensor comprises a floating diffusion region disposed at one side of a transfer gate within a substrate and a photo detecting column disposed at the other side of the transfer gate opposing to the floating diffusion region within the substrate. The photo detecting column comprises a doped sensing layer with a doping type opposite to that of the substrate. The photo detecting column and the substrate are in contact with each other at a junction interface comprising one or more recessed portions. By forming the junction interface with recessed portions, the junction interface is enlarged compared to a previous p-n junction interface without recessed portions, and thus a full well capacity of the photodiode structure is improved.

Claim (Index 13):
The CMOS image sensor of  claim 12 , wherein the first, second, third and fourth sensing pixels share a same floating diffusion region.
