Abstract: An image sensor includes a first conductivity type first impurity region surrounded by a pixel isolation layer surrounds; a first conversion device isolation layer intersecting the first impurity region in a first direction; a second conductivity type second impurity region disposed on a first side surface of the first conversion device isolation layer; a second conductivity type third impurity region disposed on a second side surface of the first conversion device isolation layer opposite the first side surface; and a second conversion device isolation layer intersecting the first impurity region in a second direction perpendicular to the first direction. The second impurity region and the third impurity region are disposed inside the first impurity region.
