3D IMAGE SENSOR AND ELECTRONIC SYSTEM INCLUDING THE SAME

摘要

PURPOSE: A 3D image sensor and an electronic system including the same are provided to improve performance by vertically laminating a color filter and an organic photoconductive conversion layer for sensing depth information. CONSTITUTION: A unit pixel(100) includes a color filter(150) and an infrared sensing part. The color filter selectively absorbs visible light and converts the light into electricity. A readout circuit reads out the image information sensed from a pixel array. An infrared sensing part includes a first electrode(141), a second electrode(142), and an organic photoconductive conversion layer(130). The organic photoconductive conversion layer is formed between the first electrode and the second electrode. The visible light passes through the organic photoconductive conversion layer, and infrared light is selectively absorbed for photoelectric conversion.
