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 pixel region and a pad region, a first conductive pad on the substrate in the pad region, a micro lens layer on the substrate in the pixel region, and a first protective pattern covering the pad region and exposing the first conductive pad. The first protective pattern and the micro lens layer include the same material, and the first protective pattern and the micro lens layer are apart from each other.

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.
