ABSTRACT:
An image sensor, in which, a planarized layer is formed on a semiconductor substrate including a pixel array region, an optical black region, and a logic region to cover a photo sensing unit array in the pixel array region, a patterned metal layer is formed on the planarized layer corresponding to the pixel array region and the logic region, but not the optical black region. An optical black layer is formed in the optical black region after a passivation layer is formed and before a color filter array is formed at a temperature less than about 400° C., and preferably contains metal material.
