Abstract
An optical sensor structure is provided. The optical sensor structure includes a substrate, a light sensing unit, a peripheral wall, and a reflective layer. The substrate includes a plurality of metal pads. The light sensing unit is disposed on the substrate and electrically connected to the plurality of metal pads. The peripheral wall is disposed on the substrate, and the peripheral wall and the substrate define an accommodating space. The metal pads and the light sensing unit are positioned in the accommodating space. The reflective layer is disposed in the accommodating space and surrounds the light sensing unit.
