Abstract: An image sensor includes a first substrate including pixel regions, each of the pixel regions including a photoelectric conversion region, color filters on the pixel regions, the color filters on a first surface of the first substrate, micro lenses on the color filters, and a lens coating layer on the micro lenses. The lens coating layer includes a first coating layer and a second coating layer, the second coating layer is on the first coating layer, the first and second coating layers include a same material, and a density of the second coating layer is greater than a density of the first coating layer.

Abstract: An image sensor includes a substrate having a plurality of pixel regions, a lower layer on the substrate; a plurality of color filters on the lower layer, and a micro-lens layer on or covering top surfaces of the color filters. The micro-lens layer extends to a location between two of the color filters and contacts the lower layer on one of the pixel regions. The color filters are spaced apart from the lower layer.

Abstract: An image sensor includes a substrate including a first region and a second region disposed in a periphery of the first region. The first region includes a plurality of unit pixels and a color filter structure, and the second region includes a dummy structure including a second color filter and a plurality of dummy lenses on the second color filter. The color filter structure includes a first extension portion extending in a first direction and a second extension portion extending in a second direction, and the dummy structure includes a third extension portion extending in the first direction and a fourth extension portion extending in the second direction. A first micro-lens, a second micro-lens, and a third micro-lens are in a first corner portion, and a first dummy lens, a second dummy lens, and a third dummy lens are in the second corner portion.
