Patent ID: 7723763

Claim:
A color with multi-primary pixels photodetector apparatus having periodic metal hole array by using a generation area of surface plasma resonance effect, comprising: a N-type semiconductor substrate; a P + polar area formed in the N-type semiconductor substrate; an optical-electrical conversion area formed between the P + polar area and the N-type semiconductor substrate; a dielectric layer formed on the N-type semiconductor substrate; and a metal layer formed on the dielectric layer, the metal layer being used as a color photodetector terminal, and the metal layer being selected from a group consisting of aluminum and copper on the optical-electrical conversion area having a periodic metal hole array, wherein a size of a metal hole for the periodic metal hole array being about from 0.2 μm to 10 μm and a size of a period for the periodic metal hole array being about 0.6 μm, 0.8 μm, and 1.0 μm, which being a generation area of surface plasma resonance effect.
