Abstract

An image sensor includes a light-sensing element that generates charge in response to incident light, a storage diode formed in a substrate, wherein the storage diode stores the charge generated by the light-sensing element, a floating diffusion region formed in a top surface of the substrate and spaced apart from the storage diode, and a transfer gate at least partially buried under the top surface of the substrate, wherein the transfer gate controls the transfer of the charge from the storage diode to the floating diffusion region.
