Patent ID: 7504614

Claim:
An image sensor comprising: a photoelectric transformation region formed in a semiconductor substrate; a stacked interconnection element formed proximate to a peripheral portion of the photoelectric transformation region, the stacked interconnection element comprising a stacked plurality of interlayer dielectric films, wherein each interlayer dielectric film comprises an interconnection layer; a color filter layer formed in relation to the stacked interconnection element on the photoelectric transformation region; a shield insulation film interposed between the color filter layer and the photoelectric transformation region, wherein the shield insulation layer functions as an etch-stop layer interposed between the color filter and the photoelectric transformation region, wherein the color filter layer is formed to a depth defined at least in part by the etch-stop layer; a continuous passivation layer interposed between the color filter layer and the stacked interconnection element and between the shield insulation film and the color filter layer; and a microscopic lens formed on the color filter layer.
