Abstract
An image sensor includes a substrate that includes a trench that defines pixel regions and a deep isolation pattern provided between the pixel regions and in the trench. The deep isolation pattern includes first and second insulating liner patterns disposed on first and second inner side surfaces of the trench, first and second lower insulating patterns disposed on lower inner side surfaces of the first and second insulating liner patterns and an isolation pattern provided between the first and second lower insulating patterns and that extends through the substrate. The deep isolation pattern further includes a first air gap region that is a space enclosed by the first insulating liner pattern, the first lower insulating pattern, and the isolation pattern, and a second air gap region that is a space between the second insulating liner pattern, the second lower insulating pattern, and the isolation pattern.
