METHOD FOR FABRICATING IMAGE SENSOR

摘要

PURPOSE: A method for fabricating an image sensor is provided to lessen a mechanical impact in a back surface polishing process by forming a lens protection layer on a micro lens of an image sensor, and to maximize the characteristic of the micro lens by eliminating the lens protection layer after the back surface polishing process. CONSTITUTION: An overcoating layer(213) is formed on a color filter(212). A micro lens(214) is formed in a predetermined position on the overcoating layer. A lens protection layer is formed to sufficiently cover the micro lens. A back surface polishing process is performed. The lens protection layer is eliminated.
