Patent ID: 7858446

Claim:
A fabrication method of a sensor-type semiconductor package, comprising steps of: providing a wafer having a plurality of sensor chips; attaching light-permeable bodies to the sensor chips, wherein, each light-permeable body has a first surface, a second surface opposing to the first surface and a planar size smaller than that of a respective one of the sensor chips, a covering layer is mounted on the first surface, a ring-shaped adhesive layer is mounted on the second surface, and the light-permeable bodies are attached to the sensor chips through the ring-shaped adhesive layers on the second surfaces thereof; singulating the wafer so as to obtain a plurality of separated sensor chips with the light-permeable bodies attached thereon; providing a substrate module having a plurality of substrates; attaching the separated sensor chips to the substrates; electrically connecting the sensor chips to the substrates; forming an encapsulant on the substrate module for encapsulating the sensor chips and the light-permeable bodies by a molding process; cutting the encapsulant along edges of the light-permeable bodies to edges of the covering layers; removing the covering layers with a portion of the encapsulant mounted thereon so as to expose the light-permeable bodies from the encapsulant; and cutting between the substrates so as to obtain a plurality of sensor-type semiconductor packages.
