Abstract:
1. A backside-illumination-type image device comprising: a substrate pattern defining an opening and comprising a portion of a photodiode for receiving light through a top surface; a plurality of stacked metal interconnection patterns and an interlayer dielectric layer formed beneath a bottom surface of the substrate pattern that is opposite the top surface of the substrate pattern; and a plurality of first contacts formed in the interlayer dielectric layer to electrically connect the substrate pattern and a first metal interconnection pattern of the plurality of stacked metal interconnection patterns positioned closest to the substrate pattern, wherein a height of the opening equals a height of the substrate pattern, such that an exposed portion of a top surface of the interlayer dielectric layer provides a bottom surface of the opening, and an external connection electrode is positioned on the bottom surface of the opening.
