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.
