Abstract

A semiconductor structure includes a grating coupler structure, a circuit component separated from the grating coupler structure, an inter level dielectric layer, a capping layer over the inter level dielectric layer, and a passivation layer over the capping layer. The inter level dielectric layer has a first refractive index, the capping layer has second refractive index, and the passivation layer has a third refractive index. The second refractive index is greater than the first refractive index, and is greater than the third refractive index.
