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 6):
The method of forming an image sensor according to  claim 4 , wherein a first type of doped ions are provided in the well region; a second doped type of ions are provided in the photoelectric doped region, the second type of doped ions and the first type of doped ion are opposite in conduction types; and a third type of doped ions are provided in the floating diffusion region, the third type of doped ions and the first type of doped ions are opposite in conduction types.
