1. A solid-state imaging apparatus in which a plurality of pixels are laid out in a matrix form, each of the pixels having an imaging region having a photoelectric conversion portion, a first transfer transistor configured to transfer electric carriers from the photoelectric conversion portion, an electric-carrier accumulation portion to which the electric carriers are transferred from the first transfer transistor, a second transfer transistor configured to transfer electric carriers accumulated in the electric-carrier accumulation portion, and a floating diffusion to which the electric carriers are transferred from the second transfer transistor, the solid-state imaging apparatus comprising:
an active region having the photoelectric conversion portion, the electric-carrier accumulation portion, and the floating diffusion, and an element isolation region having an insulator defining the active region; and in planer view, the width of the active region in the electric-carrier accumulation portion under a gate of the first transfer transistor is larger than the width of the active region in the photoelectric conversion portion under the gate of the first transfer transistor. |
