Patent ID: 7129982

Claim:
An integrated pixel sensor structure comprising: a set of at least three light sensitive diodes, the set of at least three light sensitive diodes including an i-layer placed on top of an n-layer, a p-layer placed on top of the i-layer, and a transparent conductor placed on top of the p-layer; a protective layer coupled to the transparent conductor, a set of separated echelon diffraction grating elements for producing complementary colors and to protect the set of at least three light sensitive diodes, the protective layer disposed between adjacent echelon diffraction grating elements of the set of separated echelon diffraction grating elements, the set of grating elements are placed on top of the transparent conductor, wherein the protective layer is of a sol gel material, the protective layer covers a portion of the transparent conductor not covered by the set of separated echelon diffraction grating elements, and the integrated pixel sensor structure not including a lens.
