| 摘要 |
The present invention discloses a progressive-refractivity antireflection layer and a method for fabricating the same to eliminate light reflection occurring in an interface. The present invention is characterized in being fabricated via depositing a first material and a second material, and having a refractivity (neff) gradually varying with a thickness thereof and ranging between a refractivity (n1) of the first material and a refractivity (n2) of the second material. No matter at what thickness the refractivity (neff) of the antireflection layer is measured, the refractivity (neff) meets an effective medium theory expressed by an equation: neff={n12f+n22(1-f)}1/2, wherein f is a filling ratio of the first material of the antireflection layer.
