ABSTRACT:
A charge coupled device image sensor which can prevent smear and improve sensitivity, including a substrate of a first conductive type, a first well of a second conductive type formed on one side of said substrate, a second well of the second conductive type formed on the other side of said substrate, a pair of photo-detecting areas formed adjoining in said first well, a pair of charge transfer areas formed close to each photo-detecting area and adjoining in said second well, a channel stop area formed between said adjoining photo-detecting areas and said charge transfer areas and for isolating each of the areas,.respectively, high-density impurities areas of the second conductive type being formed on the upper surface of said photo-detecting area, a gate insulation film formed on the whole substrate, a pair of transfer gates formed on said gate insulation film at the upper side of each charge transfer area, a insulation film for encompassing said transfer gate and being formed on said gate insulation film except said pair of photo-detecting areas, a light-shading film formed on said insulation film except said pair of photo-detecting areas, a leveling substrate formed on the whole substrate, and, a micro lens formed said leveling substrate at the upper side of said pair of photo-detecting areas.
