Abstract
A backside-illuminated image sensor and a method of manufacturing the same are disclosed. The backside-illuminated image sensor is capable of improving sensitivity by including a scattering layer in a substrate that may result in incident light having a path greater than the thickness of the substrate and, simultaneously, of additionally enhancing light sensitivity with respect to a specific wavelength or wavelength band of light passing through one of a plurality of different color filters by a varying depth or thickness of the scattering layer for each unit pixel in the image sensor.
