    Abstract: A semiconductor image sensor includes a substrate and an isolation insulating pattern having a trench therein, on the substrate. A lower transparent electrode is provided within the trench. This lower transparent electrode includes a first layer and a different second layer on the first layer. An organic photoelectric layer is provided on the lower transparent electrode, and an upper transparent electrode is provided on the organic photoelectric layer. The first layer may contact a bottom and a side surface of the trench, and may have a seam therein, which is at least partially filled by a portion of the second layer. The first layer may have a higher light transmission efficiency relative to the second layer and a lower electrical resistance relative to the second layer.

    Abstract: Image sensors with improved performance and a higher degree of integration are provided. The image sensors include a substrate including a first surface and a second surface opposite to each other, a first organic photoelectric conversion layer on the first surface of the substrate, a first penetration via connected to the first organic photoelectric conversion layer and extending through the substrate, a first floating diffusion region in the substrate adjacent to the second surface of the substrate, and a first transistor structure on the second surface of the substrate, wherein the first transistor structure includes a semiconductor layer configured to connect the first penetration via and the first floating diffusion region, a gate electrode on the semiconductor layer, and a gate dielectric film between the semiconductor layer and the gate electrode.
