Abstract: An image sensor that includes a substrate including a first photodiode (PD) region and a second PD region adjacent to the first PD region; a first PD having a first area in the first PD region; a second PD in the second PD region, the second PD having a second area smaller than the first area; a micro-lens on the substrate and covering the first PD region; and a light splitter between the substrate and the micro-lens, the light splitter including a material having a refractive index different from a refractive index of the micro-lens. The light splitter extends from the first PD region to the second PD region.
