Abstract: Disclosed is an image sensor comprising a first substrate including pixel sections each of which includes a photoelectric conversion region; a plurality of color filters on the pixel sections and on a first surface of the first substrate, and a plurality of microlenses on the color filters. An array of the microlenses includes a repetitive periodic structure. The periodic structure includes a first microlens, a second microlens, and a third microlens that are sequentially arranged adjacent to each other along a first direction. A first spacing in the first direction between the first and second microlenses is substantially the same as a second spacing in the first direction between the second and third microlenses. A first pitch in the first direction between the first and second microlenses is different from a second pitch in the first direction between the second and third microlenses.

Abstract: An image sensor includes a first substrate including pixel regions, each of which comprises a photoelectric conversion region, color filters provided on the pixel regions, respectively, the color filters provided on a first surface of the first substrate, and micro lenses provided on the color filters, respectively. First period structures repeatedly arranged in a first direction are defined by the micro lenses. Each of the first period structures includes a first micro lens and a second micro lens of the micro lenses. At least one of a size, a curvature, a material or a shape of the first micro lens is different from at least one of a size, a curvature, a material or a shape of the second micro lens. A first arrangement period of the first period structures is equal to or greater than twice a pixel pitch of the pixel regions.
