Abstract
A method for fabricating an image sensor, wherein the method comprises steps as follows: Firstly, a transparent substrate is formed on a working substrate. Pluralities of micro lens are formed in the transparent substrate, wherein the lenses have a refraction ratio differing from that of the transparent substrate. Subsequently, a color filter is formed on the lenses. Afterward, the color filter is engaged with an image sensing device by flipping around the working substrate.
