Example embodiments may provide methods of manufacturing an image sensor. Example methods of manufacturing an image sensor may include forming a photoelectric converter in a semiconductor substrate, forming an interlayer insulating film covering a surface of the semiconductor substrate, forming metal wires and an inter-metal insulating film filling between the metal wires on the interlayer insulating film, forming openings above the photoelectric converter by removing a part of the inter-metal insulating film and the interlayer insulating film, curing the surface above the photoelectric converter by irradiating light into the openings, and/or forming a light transmitter filling the openings.
