Abstract:
1. An image sensor, comprising: a substrate including first and second surfaces facing each other and a plurality of pixel regions, the plurality of pixel regions being configured such that, when the second surface is exposed to a light, the light is incident on the pixel regions through the second surface; photoelectric conversion parts in the pixel regions of the substrate, respectively; and gate electrodes provided on the photoelectric conversion parts, at least one of the gate electrodes on at least a first photoelectric conversion part, from among the photoelectric conversion parts, including a buried portion in the substrate, the buried portion including a flat bottom surface and a rounded lower corner, the first photoelectric conversion part being in a first pixel region, from among the plurality of pixel regions, at least the first pixel region, from among the plurality of pixel regions, including an isolation pattern separating the first pixel region from other pixel regions of the plurality of pixel regions, the isolation pattern including, at least the first pixel region, from among the plurality of pixel regions, further including,
