Abstract
The invention provides a sensor-type semiconductor package and fabrication method thereof. The fabrication method includes steps of: attaching a sensor chip to a chip carrier; electrically connecting the sensor chip and a chip carrier via a plurality of bonding wires; mounting a light-permeable body to the sensor chip with an adhesive layer as a partition therebetween, wherein the planar size of the light-permeable body is larger than a predefined planar size of the sensor-type semiconductor package to be formed; forming an encapsulant on the chip carrier for encapsulating the sensor chip and the bonding wires with the upper surface of the light-permeable body being exposed from the encapsulant; and cutting through the light-permeable body, the encapsulant and the chip carrier according to the predefined planar size. Accordingly the contacting area between the cut light-permeable body and the cut encapsulant increased and the bonding therebetween is reinforced.
