Abstract: An image sensor including: a substrate which includes a first surface and a second surface opposite each other; a plurality of pixels, each pixel including a photoelectric conversion layer in the substrate; a pixel separation pattern disposed in the substrate and separating the pixels; a surface insulating layer disposed on the first surface of the substrate; conductor contacts disposed in the surface insulating layer; and a grid pattern disposed on the surface insulating layer, wherein the pixel separation pattern includes a first portion and a second portion arranged in a direction parallel to the first surface of the substrate, and the conductor contacts are interposed between the first portion of the pixel separation pattern and the grid pattern and are not interposed between the second portion of the pixel separation pattern and the grid pattern.

Abstract: An image sensor is provided. An image sensor includes: a substrate including an active pixel sensor region, an optical black sensor region, and a boundary region provided between the active pixel sensor region and the optical black sensor region; a photoelectric conversion element provided inside the substrate on the boundary region; a passivation layer provided on the substrate; a grid trench formed on the boundary region of the substrate and extending from an upper surface of the passivation layer toward an inside of the passivation layer; grid patterns, each of the grid patterns being provided on the passivation layer on each of the active pixel sensor region and the boundary region of the substrate, at least a part of a grid pattern being provided inside the grid trench; and a color filter provided between the grid patterns.
