Abstract
In a solid-state image pick up device, a first conduction type semiconductor layer which has a first surface side. A second surface side which is located the opposite side of the first surface side and an image sensor area. A photo-conversion area which is configured in the first surface side and charges electron by photoelectric conversion. A first diffusion area of second conduction type for isolation, wherein the first diffusion area surrounds the photo-conversion area and extends from the first surface side to the middle part of the semiconductor layer and a second diffusion area of second conduction type for isolation, wherein the second diffusion area extends from the second surface side to the bottom of the first diffusion layer.
