Patent ID: 7910954

Claim:
An image sensor element, comprising: a first image sensor element portion sensitive to radiation of a first wavelength range, wherein the first image sensor element portion comprises a first active material having a first bandgap, said first bandgap corresponding to an upper boundary of said first wavelength range; a second image sensor element portion sensitive to radiation of a second wavelength range, said second wavelength range being at least partially different from said first wavelength range, wherein said second image sensor element portion comprises a second active material having a second bandgap, said second bandgap corresponding to an upper boundary of said second wavelength range and being different from said first bandgap; and a third image sensor element portion sensitive to radiation of a third wavelength range, said third wavelength range being at least partially different from said first wavelength range and at least partially different from said second wavelength range, wherein said third image sensor element portion comprises a third active material having a third bandgap, said third bandgap corresponding to an upper boundary of said third wavelength range and being different from said first bandgap and said second bandgap, wherein the first active material, the second active material and the third active material are semiconductor materials, and wherein at least one active material of the group comprising said first active material, said second active material and said third active material comprises semiconductor quantum wells.
