Abstract
Image sensors are provided. The image sensor may include a photodiode formed in a substrate, a lower interlayer dielectric layer formed over the substrate, a drive transistor gate electrode formed over the lower interlayer dielectric layer, and a transfer transistor gate electrode including an upper portion and a lower portion. The upper portion of the transfer transistor gate electrode may be formed over the drive transistor gate electrode. The lower portion of the transfer transistor gate electrode may be formed in a pillar shape and vertically extends from the upper portion of the transfer transistor gate electrode through the drive transistor gate electrode and the lower interlayer dielectric layer into the substrate.
