Abstract:
1. An image sensor comprising: a plurality of unit color cells coloring externally input lights in red, green, and blue colors respectively having different wavelengths; a plurality of photodiodes arranged in an active region of a semiconductor substrate, generating and storing a series of optical charges by receiving red, green, and blue colored lights which have been transmitted from the respective unit color cells; an intermediate layer transferring the red, green, and blue colored lights, which have been transmitted from the unit color cells, to the photodiodes; and a plurality of partial light-shielding layers formed on portions of the intermediate layer, partially shielding a particular colored light including a red colored light and a green colored light transferred to the photodiodes through the intermediate layer, wherein a first partial light-shielding layer shielding the green colored light has a thickness between 1/20 and 1/10 of a second partial light-shielding layer shielding the red colored light so that a permeation position of the red colored light coincides with a permeation position of the green colored light and a permeation position of the blue colored light.
