| 摘要 |
An anti-reflective image sensor and method of fabrication are provided, the sensor including a substrate; first color sensing pixels disposed in the substrate; second color sensing pixels disposed in the substrate; third color sensing pixels disposed in the substrate; a first layer disposed directly on the first, second and third color sensing pixels; a second layer disposed directly on the first layer overlying the first, second and third color sensing pixels; and a third layer disposed directly on portions of the second layer overlying at least one of the first or second color sensing pixels, wherein the first layer has a first refractive index, the second layer has a second refractive index greater than the first refractive index, and the third layer has a third refractive index greater than the second refractive index.
