Abstract
An image sensor and a method of manufacturing the same are disclosed. A passivation layer on an interlayer dielectric layer has different thicknesses for neighboring pixels. Consequently, a phase of light incident on a pixel is out of phase with light incident on an adjacent pixel before it reaches a photodiode. As a result, diffraction of the incident light results in destructive interference between the pixels. Thus, cross talk between adjacent pixels can be prevented.
