Abstract:
The present disclosure provides an image sensor, and a forming method and a working method thereof. The image sensor includes: a substrate, provided with a well region part of the well region having a photoelectric doped region, the well region including a second region, a first region and a third region located on two sides of the second region, the first region and the third region being adjacent to the two sides of the second region respectively; a first gate structure, located on a surface of the second region of the well region; a second gate structure, located on a surface of the first region of the well region; and a floating diffusion region, located in the third region of the well region, the floating diffusion region being adjacent to the first gate structure. The image sensor can reduce an image lag while increasing the full well capacity.

Claim (Index 3):
The image sensor according to  claim 1 , wherein an illumination face is on the front surface of the substrate, and wherein the first gate structure and the second gate structure are located on the surface of the non-illumination face on the back surface of the substrate.
