Abstract: A light sensor structure and the manufacturing method thereof are disclosed. The light sensor structure includes a substrate with a first surface and a second surface opposite to each other. A light sensing element including a light sensing area is disposed on the first surface. A reflection layer is disposed on the second surface. The reflection layer covers a portion of the second surface aligning with the light sensing area.
