Abstract

A semiconductor image sensing structure includes a substrate, an isolation structure, an anti-reflection structure, at least one optical element and a transistor. The substrate has at least one photodiode region. The isolation structure is disposed in the substrate and surrounds the photodiode region. The anti-reflection structure covers the photodiode region. The optical element is disposed over the anti-reflection structure and corresponds to the photodiode region. The transistor is disposed under the photodiode region.
