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 13):
An image sensor, comprising:\n a wiring structure; a well region comprising a demodulation region and located on the wiring structure; a photoelectric conversion region located on the well region; a microlens located on the photoelectric conversion region; and at least two transfer gate structures spaced apart from each other with the demodulation region therebetween and each comprising a vertical transfer gate extending in a thickness direction of the well region to pass through at least a part of the well region and a transfer gate insulating film surrounding the vertical transfer gate.
