Patent ID: 10020333

Abstract:
In this solid-state imaging device, the sameness of the potential distributions in pixels, in a region from a photodiode of a transfer transistor to a floating diffusion in a charge transfer path, is improved. The solid-state imaging device includes a first transfer transistor including a first photodiode, a first gate electrode, and a first floating diffusion, a second transfer transistor including a second photodiode, a second gate electrode, and a second floating diffusion, a third transfer transistor including a third photodiode, a third gate electrode, and a third floating diffusion, and a reset transistor including a diffusion layer, which is a source or drain region, and a reset gate. The first to third floating diffusions and the diffusion layer of the reset transistor are separated from each other, and are electrically connected to each other via an interconnect. The first to third photodiodes are arrayed one-dimensionally.
