摘要 |
An image sensor with improved productivity and sensitivity is provided. The image sensor includes a plurality of unit pixels, each unit pixel including an oxide film formed upon a semiconductor substrate; a gate electrode formed on the oxide film; a photodiode N-type region formed within the semiconductor substrate and interfacing with the oxide film, which is space apart from the gate electrode by a predetermined distance and disposed on one side of the gate electrode; and a floating diffusion region formed within the semiconductor substrate and interfacing with the oxide film, which is spaced apart from the gate electrode by a predetermined distance and is disposed on the other side of the gate electrode.
