Abstract
A semiconductor structure including a substrate, a light sensing device and a light-guiding structure is provided. The light sensing device is disposed in the substrate. The light-guiding structure is located above the light sensing device. The light-guiding structure has a top surface and a bottom surface opposite to each other, and the bottom surface is closer to the substrate than the top surface. A position of a minimum width of the light-guiding structure is located between the top surface and the bottom surface.
