Abstract
The present invention relates to a complementary metal oxide semiconductor (CMOS) image sensor. Particularly, a unit pixel of the complementary metal oxide semiconductor (CMOS) image sensor, wherein the unit pixel has a rectangular shape and is defined with the top region and the bottom region of which area is larger than that of the top region, the unit pixel including: a photodiode region disposed in entire areas of a bottom region of the unit pixel; a reset gate, a drive gate and a selection gate disposed in an upper part of a top region of the unit pixel; a multi-floating diffusion region disposed with a uniform size at least at two corners of the photodiode region; and a transfer gate disposed in an upper part of the photodiode region to thereby define the multi-floating diffusion region.
