Image sensor and method of manufacturing the same |
摘要 |
An image sensor and a method of manufacturing same is disclosed. The image sensor implements a reflecting film formed on a front surface of a substrate having a back-illuminated photodetector. The reflecting film operates to reflect wavelengths of light that were not received by the photodetector back to the photodetector to increase the overall sensitivity of the image detector. The reflective film is formed by layering different thicknesses of material with different indices of refraction, resulting in a high reflectance.
