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 14):
The CMOS image sensor of  claim 13 ,\n wherein the first photo detecting column and the first transfer gate of the first sensing pixel and the second photo detecting column and the second transfer gate of the second sensing pixel are symmetric along a separation line separating the first sensing pixel and the second sensing pixel; wherein the third photo detecting column and the third transfer gate of the third sensing pixel and the fourth photo detecting column and the fourth transfer gate of the fourth sensing pixel and are symmetric along a separation line separating the third sensing pixel and the fourth sensing pixel.
