SOLID STATE IMAGE PICK-UP DEVICE, AND PIXEL

摘要

A pixel 10 includes a photodiode PD which is provided between a first barrier region 21 forming a first potential barrier B1 and a second barrier region 27 forming a second potential barrier B2, a first floating diffusion region F1 which is provided adjacent to the first barrier region 21, and to which a first electric charge generated in the photodiode PD is transferred, and a second floating diffusion region F2 which is provided adjacent to the second barrier region 27, and into which a second electric charge generated in the photoelectric conversion region PD flows, and in which a part of the flowing-in second electric charge is accumulated. The second potential barrier B2 is lower than the first potential barrier B1.
