Charge-coupled device having on-chip lens

摘要

In a color CCD (charge-coupled device) imaging device where chromatic filter components are formed on sensor units functioning as pixels, respectively, and small condenser lenses are provided on the respective chromatic filter components, it is so constructed that areas of the small condenser lenses are varied, depending upon film thickness of the respective chromatic filter components. Then, the sensitivity increasing rates for the respective pixels of the color CCD imaging device are uniformed.
