摘要： An image sensor, includes a semiconductor substrate; a photosensor having, a first photosensing region including a first stack of one or more layers of transparent materials overlying the substrate, the first photosensing region having a spectral response having peaks and valleys, and a second photosensing region including a second stack of one or more layers of transparent materials overlying the substrate, the second photosensing region having a spectral response having peaks and valleys; and wherein at least one peak or valley of the spectral response of the first region is matched to at least one valley or peak respectively of the spectral response of the second region such that the average spectral response of the photosensor is smoother than the individual spectral response of either the first or second photosensing regions.
