Abstract: An image sensor includes a substrate including a first region and a second region. A photodiode is in the first region of the substrate. A color filter array layer is on the first region of the substrate. The color filter array layer includes color filters. A pad structure extends through an upper portion of the second region of the substrate and protrudes upwardly over an upper surface of the substrate in a vertical direction substantially perpendicular to the upper surface of the substrate. A dummy structure is spaced apart from the pad structure on the second region of the substrate.
