Semiconductor structure
A semiconductor structure includes a substrate, a plurality of image sensing devices formed in the substrate, at least a passivation layer formed on the substrate, a plurality of first metal patterns formed on the passivation layer, a plurality of gaps formed between the first metal patterns, an insulating layer lining the gaps, and a plurality of light-guiding structures respectively formed in the gaps. The light-guiding structures respectively include an anchor portion and a body portion, and bottom surfaces of the anchor portions being lower than top surfaces of the first metal patterns.
