PROBLEM TO BE SOLVED: To provide a technique advantageous for enhancement of linearity between the illuminance (amount of incident light) and potential change appearing in a floating diffusion layer and reduction of dark current noise.SOLUTION: A photoelectric conversion device PV has an element isolation 91 arranged to surround an active region including a first region and a second region in contact with each other by a virtual line VL, a first conductivity type charge storage region 21, a first conductivity type floating diffusion region 41, a gate electrode G, and a second conductivity type first semiconductor region 100. The width of the second region in a direction parallel with the virtual line VL is narrower than the width of the first region in that direction, and the gate electrode G has a portion connecting the vertical boundary of the second region and the element isolation 91, and a portion across the boundary of the second region and first region.SELECTED DRAWING: Figure 1 |
