Abstract:
1. A complementary metal oxide semiconductor (CMOS) image sensor comprising: a plurality of photodiodes formed in the surface of a semiconductor substrate; a first planarization layer formed on the semiconductor substrate having the photodiodes; color filter layers formed on the first planarization layer corresponding to the plurality of photodiodes, the color filter layers being spaced apart from each other by a predetermined interval; a second planarization layer formed in a convex shape on the semiconductor substrate having the color filter layers; a light blocking layer formed in the second planarization layer between each of the color filter layers, the light blocking layer formed from the top surface of the second planarization layer to the bottom surface of the second planarization layer; and a plurality of microlenses formed on the second planarization layer corresponding to the color filter layers.
