A method for manufacturing CMOS image sensor is provided. The method includes: forming an interlayer dielectric on a semiconductor substrate on which a plurality of photodiodes are formed; forming a plurality of color filters at regular intervals on the interlayer dielectric; forming a planarization layer on an entire surface of the semiconductor substrate including the color filters; forming sacrificial resist patterns on the planarization layer, the sacrificial resist patterns being spaced apart from each other; forming spacers at sidewalls of the sacrificial resist patterns; removing the sacrificial resist patterns; forming a resist layer on the planarization layer on which only the spacers remain; removing the spacers; and reflowing the resist layer at a predetermined temperature to form a microlens.
