Abstract: The present invention relates to image sensors and method of manufacturing the same. The image sensor may include a substrate having pixel regions in which photoelectric-conversion devices and storage node regions spaced apart from each other; a lower contact via between the photoelectric conversion-devices in the pixel regions; a first insulating layer on the lower contact via and having an opening; an upper contact via electrically connected to the lower contact via through the first insulating layer and protruding from the first insulating layer; a second insulating layer surrounding the first insulating layer and the upper contact via, an upper surface of the second insulating layer in the opening defining a trench; a color filter filling the trench; a protective film exposing the upper contact via; a first transparent electrode on the protective film that contacts the upper contact via; and an organic photoelectric layer on the first transparent electrode.

Abstract: An image sensor may include a substrate having a plurality of pixel regions in which photoelectric-conversion devices and storage node regions spaced apart from each other; a lower contact via between the photoelectric conversion-devices in the plurality of pixel regions; a first insulating layer on the lower contact via and having an opening; an upper contact via electrically connected to the lower contact via through the first insulating layer and protruding from the first insulating layer; a second insulating layer to surround the first insulating layer and the upper contact via, an upper surface of the second insulating layer in the opening defining a trench; and a color filter filling the trench. A protective film exposing the upper contact via, a first transparent electrode on the protective film and in contact with the upper contact via, and an organic photoelectric layer formed on the first transparent electrode may be provided.
