IMAGE SENSOR AND METHOD OF MANUFACTURING THE SAME

An image sensor and a method of manufacturing the image sensor are provided. The image sensor includes: a substrate comprising a pixel area, a first side, and a second side opposite to the first side, wherein the pixel area includes pixels and light is incident to the second side; a photodiode arranged in each of the pixels of the substrate; a pixel separation structure arranged in the substrate to separate the pixels from each other and including a conductive layer therein; and a voltage-applying wire layer spaced apart from the conductive layer and arranged to surround at least a portion of an outer portion of the pixel area. The conductive layer has a mesh structure that is a single unitary structure, and the voltage-applying wire layer is electrically connected to the conductive layer through at least one contact.
