Semiconductor structure comprising a stacked dielectric layer

A semiconductor structure, comprising:

• a gate, disposed on a substrate;
• an oxide channel layer, disposed on the substrate and stacked on the gate;
• a gate insulating layer, disposed between the gate and the oxide channel layer;
• a source, disposed at a side of the oxide channel layer;
• a drain, disposed at the side of the oxide channel layer, and the source and the drain are configured in parallel, wherein a portion of the oxide channel layer is exposed between the source and the drain;
• a dielectric stacked layer, disposed on the substrate, and comprising a plurality of first inorganic dielectric layers with a first refractive index and a plurality of second inorganic dielectric layers with a second refractive index, wherein the plurality of first inorganic dielectric layers and the plurality of second inorganic dielectric layers are not alternately stacked, and at least one of the plurality of first inorganic dielectric layers directly covers the source, the drain and the portion of the oxide channel layer, and the first refractive index is smaller than the second refractive index.
