<p>Provided is a pixel array of a 3D CMOS image sensor, which belongs to the field of integrated circuits. From bottom to top, the pixel array comprises in sequence: a substrate, a sensor layer being provided in the substrate and being used for conducting a photoelectric conversion on incident light in an optical channel; a metal layer which is used for transmitting an electrical signal, on which the photoelectric conversion is conducted, to a peripheral circuit for processing; a micro-lens layer which is used for focusing light rays which are irradiated into the optical channel to form the incident light; and a light shading layer which is used for enabling the direction of the incident light sensed by a sensing layer in each pixel in an odd column and the direction of the incident light sensed by a sensing layer in each pixel in an even column to be distributed at two sides of a normal direction of a pixel array respectively, so that digital images which simulate left and right eye channels are formed by way of the processing of the peripheral circuit. In the present invention, based on a monolithic image sensor, the 3D stereoscopic vision is achieved, and the costs of the 3D stereoscopic vision are reduced.</p> |
