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 1):
An image sensor, comprising:\n a substrate having a front surface to receive light and a back surface opposite to the front surface; a well region, doped with a first type of ions, provided in the back surface of the substrate; a first region, a second region, and a third region sequentially disposed in the well region, wherein the first and third regions are on two sides of the second region; a photoelectric region doped with a second type of ions disposed in the first region; a first gate structure located on the back surface of the substrate aligned with the second region; a second gate structure, located on the back surface of the substrate aligned with first region; and a floating diffusion region located in the third region and next to the first gate structure.
