Abstract: An image sensor includes a substrate structure including a sensor array region and a pad region adjacent to the sensor array region. The substrate structure includes a first substrate structure and a second substrate structure. The first substrate structure is on the second substrate structure. The image sensor includes a penetrating structure including a first conductive material layer and a second conductive material layer in at least a portion of the first substrate structure. The second conductive material layer is electrically connected to the first conductive material layer and extends into the first substrate structure.
