Abstract
An image sensor includes a pixel division structure including a core and a lateral pattern structure on a sidewall of the core, the pixel division structure extending through a substrate in a vertical direction perpendicular to an upper surface of the substrate, the pixel division structure defining unit pixel regions including unit pixels. The image sensor includes a light sensing element in each of the unit pixel regions, a planarization layer on the substrate, a color filter array layer on the planarization layer, the color filter array layer including color filters, and a microlens on the color filter array layer. The lateral pattern structure includes a second lateral pattern on the sidewall of the core and a first lateral pattern on an outer sidewall of the second lateral pattern, the first lateral pattern includes silicon oxide, and the second lateral pattern includes silicon nitride containing carbon.
