An image sensor including a substrate and an interlayer dielectric layer divided into a pixel region and a logic pad region. An image sensor may include at least one of the following: a color filter, an over coating layer, and a micro lens sequentially formed over the interlayer dielectric layer in the pixel region; a top conductive layer formed over the interlayer dielectric layer of the logic pad region; an etch stop layer formed over the interlayer dielectric layer in the logic pad region and on the sides and a portion of an upper surface of a top conductive layer; and a first and second protective layers sequentially formed over the etch stop layer.
