Abstract:
An inventive solid-state imaging apparatus is provided which can improve the efficiency of the electric carrier transfer from a photoelectric conversion portion to an electric-carrier accumulation portion. The solid-state imaging apparatus includes an active region having the photoelectric conversion portion, the electric-carrier accumulation portion, and a floating diffusion, and an element isolation region having an insulator defining the active region. 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.

Claim (Index 1):
A photoelectric conversion 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:\n 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; wherein, in a predetermined direction in plan view, a width of the active region in the electric-carrier accumulation portion under a gate of the first transfer transistor is larger than a width of the active region in the photoelectric conversion portion under the gate of the first transfer transistor, and wherein, in the predetermined direction in plan view, the active region having the photoelectric conversion portion has a width that is larger than the width of the active region in the photoelectric conversion portion under the gate of the first transfer transistor.
