In a method of manufacturing an image sensor, a photodiode may be formed in a light receiving region of a substrate having a first surface. A conductive wiring may be formed on the first surface of the substrate. After removing a portion of the substrate opposite to the first surface, an anti-reflective layer may be formed on a second surface of the substrate. The second surface may be opposite to the first surface. The anti-reflective layer and the light receiving region may be thermally treated to cure defects including dangling bonds in the substrate and to improve a refraction index of the anti-reflective layer. The image sensor may have an enhanced light transmittance and may produce high-definition images.
