A method for manufacturing an image sensor including forming a metal line layer on a semiconductor substrate, and then forming color filters on the metal line layer, and then forming seed microlenses spaced apart on the color filters, and then cleaning the surface of the seed microlenses, and then forming a gapless microlenses on the color filters by depositing an inorganic layer on the seed microlenses and in spaces therebetween. A gapless microlens can prevent crosstalk and noise and enhance the image quality of the image sensor. Forming the microlens of thin inorganic layer can prevent cracking due to physical impacts. The adhesive force can be enhanced between the first and second organic films of the microlens by performing cleaning processes, which in turn, enhances the refractive index and light transmittance for incident light.
