Abstract
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.
