Abstract
A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, an opaque support (e.g., a ring-shaped solder mask) disposed on the sensor chip, and a light permeable layer disposed on the opaque support. The sensor chip includes a sensing region. The opaque support surrounds the sensing region, and inner lateral sides of the opaque support form a light-scattering loop wall. The light permeable layer, the light-scattering loop wall of the opaque support, and the sensor chip jointly define an enclosed space therein. When light passes through the light permeable layer and impinges onto the light-scattering loop wall at an incident angle, the light-scattering loop wall scatters the light into multiple rays at angles different from the incident angle.
