Abstract

In this paper, the structure and the performances of a CMOS image sensor with high conversion gain (CG): 240 μV/e-, high full well capacity (FWC): 200 ke-, wide spectral response: 190-1000 nm and high robustness to ultraviolet (UV) light are described. The developed CMOS image sensor was fabricated by introducing the following key technologies; small capacitance floating diffusion (FD) structure with lateral overflow integration capacitor (LOFIC) for pixel and a thin surface high concentration p+ layer with steep dopant profile for photodiode.
