Abstract:
The image sensor includes: a semiconductor substrate having a first conductivity type and including a first surface, a second surface opposite to the first surface, and a well region adjacent to the first surface. A first vertical transfer gate and a second vertical transfer gate are spaced apart from each other and extend in a thickness direction of the semiconductor substrate from the first surface to pass through at least a part of the well region. A photoelectric conversion region has a second conductivity type, which is different from the first conductivity type, is located in the semiconductor substrate between the well region and the second surface, and overlaps the first vertical transfer gate and the second vertical transfer gate in the thickness direction of the semiconductor substrate. A wiring structure is located on the first surface of the semiconductor substrate.

Claim (Index 7):
The image sensor of  claim 6 , wherein the semiconductor substrate has a plurality of recesses formed in the second surface to be sunk toward the first surface,\n wherein the image sensor further comprises scattering induction layers respectively located in the plurality of recesses and formed of an insulating material, wherein the negative fixed charge layer surrounds the scattering induction layers so that the scattering induction layers and the second surface of the semiconductor substrate are spaced apart from each other.
