IMAGE SENSING DEVICE, IMAGE SENSING SYSTEM, AND METHOD FOR MANUFACTURING IMAGE SENSING DEVICE |
摘要 |
An image sensing device includes a light-shielding film having transit portions, a first film and a second film. The second film comprises a first layer having a different refractive index from the first film. The first layer lies within at least the transit portions, and forms interfaces with the first film. The distance between the interface and the corresponding photoelectric conversion portion is greater than the distance between the photoelectric conversion portion and the lower end of the corresponding transit portion.
