Claim 17:
18. The image sensor of claim 11, wherein the deep trench further defines a second pixel region separated from the first pixel region in the first horizontal direction in the substrate,
wherein the image sensor comprises:
a second photoelectric conversion region disposed within the second pixel region; and
a second shallow trench extending from the first surface of the substrate into the substrate and configured to at least partially define a second pattern in the second pixel region,
wherein, in the plan view, the second pattern comprises a fifth corner, a sixth corner separated from the fifth corner in the first horizontal direction, a seventh corner separated from the fifth corner in the second horizontal direction, and an eighth corner separated from the sixth corner in the second horizontal direction and separated from the seventh corner in the first horizontal direction,
wherein, in the plan view, a radius of curvature of the fifth corner is less than a radius of curvature of the sixth corner.
