    Abstract: A sensor package structure includes a substrate, a sensor chip disposed on and electrically coupled to the substrate, a light-permeable layer, an adhesive layer having a ring-shape and sandwiched between the sensor chip and the light-permeable layer, and an encapsulant formed on the substrate. The adhesive layer has two adhering surfaces having a same area and a middle cross section located at a middle position between the two adhering surfaces. An area of the middle cross section is 115% to 200% of an area of any one of the two adhering surfaces. The adhesive layer can provide for light to travel therethrough, and enables the light therein to change direction and to attenuate. The sensor chip, the adhesive layer, and the light-permeable layer are embedded in the encapsulant, and an outer surface of the light-permeable layer is at least partially exposed from the encapsulant.
