More Information
Summary:A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, a plurality of adhesive rings disposed on the sensor chip, a plurality of filtering lenses respectively adhered to the adhesive rings, and an encapsulant that surrounds the above components. A sensing region of the sensor chip has a layout boundary and a plurality of sub-regions that are defined by the layout boundary and that are separate from each other. The adhesive rings are disposed on the sensing region, and each of the adhesive rings surrounds one of the sub-regions. Each of the filtering lenses, a corresponding one of the adhesive rings, and a corresponding one of the sub-regions jointly define a buffering space. The encapsulant is formed on the substrate and covers the layout boundary of the sensor chip.
