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&#xb0; C., and preferably contains metal material.

Image sensor and method of manufacturing the same

An image sensor includes a substrate, at least an optical device, at least a dielectric layer, and at least a wave-guide tube disposed upon the optical device. The wave-guide tube has an optical barrier disposed on a sidewall thereof and a filter layer filled in the wave-guide tube. The structure of the wave-guide tube has the advantages of shortening light path, focusing, and preventing undesirable crosstalk effect between different optical devices.
