Abstract
A CMOS image sensor and a method for fabricating the same in which color balance is enhanced by forming photodiodes to have a depth varied according to the wavelength of incident light to be received through a color filter layer. The predetermined depth varies, from shallow to deep, as the wavelength of the band of incident light increases, such that the predetermined depth is shallowest for the shortest wavelength, e.g., blue light, of the bands of incident light and is deepest for the longest wavelength, e.g., red, of the bands of incident light.
