Abstract

A CMOS image sensor and a method for fabricating the same is disclosed, to enhance the image-sensing efficiency by forming a concave lens area for improving the light-condensing efficiency in a planarization layer formed before a micro-lens array, in which the CMOS image sensor includes a plurality of photosensitive devices on a semiconductor substrate; an insulating interlayer on the plurality of photosensitive devices; a plurality of color filter layers in correspondence with the respective photosensitive devices, to filter the light by respective wavelengths; a planarization layer on the color filter layers, and having first micro-lens by intaglio in correspondence with the respective photosensitive patterns to condense the light secondly; and a plurality of second micro-lens layers on the planarization layer in correspondence with the respective photosensitive devices, to condense the light firstly.
