Stereoscopic image sensing module and image sensor

The invention provides a three-dimensional image sensing module and an image sensor. The three-dimensional image sensing module comprises a semiconductor substrate and a plurality of gate structures, the semiconductor substrate extends along the height direction, and the top surface of the semiconductor substrate is used as a photosensitive surface; the plurality of gate structures are respectively arranged on the outer side of the semiconductor substrate along the height direction, and the plurality of gate structures are matched with the semiconductor substrate to form a plurality of photosensitive units in the height direction. Due to the fact that the penetrating distances of the incident light of different colors in the semiconductor substrate are different, when the incident light irradiates the top face of the semiconductor substrate, the light sensing units located at different positions of the semiconductor substrate in the height direction of the semiconductor substrate can sense the light of differ
