Abstract:
A method for manufacturing a high-dynamic-range color image sensor includes (a) depositing a color filter layer on a silicon substrate having a photosensitive pixel array with a plurality of first pixels and a plurality of second pixels, to form (i) a plurality of first color filters above a first subset of each of the plurality of first pixels and the plurality of second pixels and (ii) a plurality of second color filters above a second subset of each of the plurality of first pixels and the plurality of second pixels, wherein thickness of the second color filters exceeds thickness of the first color filters, and (b) depositing, on the color filter layer, a dynamic-range extending layer including grey filters above the second pixels to attenuate light propagating toward the second pixels, combined thickness of the color filter layer and the dynamic-range extending layer being uniform across the photosensitive pixel array.

Claim (Index 6):
The method of  claim 1 , further comprising:\n in the step of depositing the color filter layer, forming a plurality of third color filters above a third subset of the photosensitive pixel array including a third subset of each of the first and second pixels, thickness of the third color filters exceeding thickness of the second color filters; and in the step of depositing the dynamic-range extending layer, forming grey filters above second pixels located under the third color filters such that thickness of the grey filters above the third color filters is less than thickness of the grey filters above the second color filters to compensate for attenuation of material of the grey filters being greater in transmission band of the third color filters than in transmission band of the second color filters.
