Patent ID: 7493713

Claim:
A method of fabricating an image sensor, comprising: forming a plurality of photoelectric conversion regions in predetermined fields of a semiconductor substrate, wherein the plurality of photoelectric conversion regions comprises first, second, and third color regions; forming a reflection protection structure on the plurality of photoelectric conversion regions by sequentially forming first, second, third, and fourth insulation films on the plurality of photoelectric conversion regions, sequentially etching the fourth, third, and second insulation films in the first color region to expose the first insulation film in the first color region, and etching the fourth insulation film in the second color region to expose the third insulation film in the second color region; and forming a plurality of color filters, including at least first, second, and third color filters on the reflection protection structure, wherein the reflection protection structure comprises at least first, second, and third portions respectively associated with one of the first, second, and third color regions.
