Abstract

The present invention relates to an image sensor and to a method for driving same. Disclosed is an image sensor which includes a first photoelectric conversion unit generating a charge by receiving a plurality of light beams other than the light beam of a first wavelength, and a second photoelectric conversion unit generating a charge by receiving the light beam of the first wavelength, wherein at least a portion of the first and second photoelectric conversion units are provided so as to be spaced apart from each other in the vertical direction.

Description

technical field [0001] The present invention relates to an image sensor and its operating method, and in particular to a Complementary Metal Oxide Silicon (CMOS) image sensor and its operating method. Background technique [0002] Complementary Metal Oxide Semiconductor Field Effect Transistor (CMOS) image sensor includes a plurality of pixels (pixel), each pixel has a photoelectric conversion element (photoelectric conversion element) to convert incident light into an electrical signal, and a metal oxide semiconductor (MOS) transistor The electrical signal can be read from each pixel. The CMOS sensor has the advantages of low voltage and low power consumption, and its application range is wide, so it is extended to be used in a camera in a mobile phone, a digital still camera, a digital video camera, or other similar items. [0003] A CMOS image sensor includes a photodiode, a dielectric layer, a color filter, and a micro lens. A photodiode is formed on the substrate as a...
