Abstract
An image sensor includes a sensor region for receiving light and generating an image data and a pad region adjacent to the sensor region, an insulation layer on the substrate, and a lower transparent electrode on the insulation layer in the sensor region, and an etch stop layer on the insulation layer in the sensor region and pad region. The etch stop layer may include silicon nitride. A height of an uppermost surface of the lower transparent electrode may be substantially equal to a height of an upper surface of the etch stop layer, with respect to the substrate.
