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 7):
An image sensor according to  claim 1 , further comprising:\n a bias voltage; a first and a second gate channels at the bottom of a first gate structure and a second gate structure, wherein the gate channel is closed when an incident light enters the photoelectric diode and photo-electrons are generated; and wherein the first and second gate channels at the bottoms of the first gate structure and the second gate structure open, and execute a reading operation, wherein the electrons are transmitted via the first gate structure into the floating diffusion region.
