    摘要: A sensor-type package and a fabrication method thereof are provided. A sensor-type chip is mounted on a substrate and is electrically connected to the substrate via bonding wires. A light-pervious body is attached to the sensor-type chip, and has one surface covered with a covering layer and another surface formed with an adhesive layer. An encapsulant encapsulates the light-pervious body. As an adhesive force between the covering layer and the encapsulant is greater than that between the covering layer and the light-pervious body, the covering layer and a portion of the encapsulant located on the covering layer can be concurrently removed, such that the light-pervious body is exposed and light can pass through the light-pervious body to be captured by the sensor-type chip. The above arrangement eliminates the need of using a dam structure as in the prior art and provides a compact sensor-type package with improved fabrication reliability.
