Original Abstract Submitted
An image sensor includes a substrate; a plurality of unit pixel regions in the substrate, each unit pixel region o including a floating diffusion region and a transfer gate electrode; and a microlens on the substrate. The transfer gate electrode includes a first connection part on a first surface of the substrate and a first extending part connected to the first connection part and extending from the first surface into the substrate. A third surface of the first extending part has a first angle with respect to the first surface of the substrate and a fourth surface of the first extending part has a second angle with respect to the first surface of the substrate. The fourth surface, the third surface, and the floating diffusion region are sequentially disposed in a direction parallel to the first surface of the substrate, and the first angle is greater than the second angle.
