Patent ID: 7358482

Claim:
A fabrication method of a packaging structure of a light-sensing element, comprising the following steps: providing a substrate, which has at least one metallization trace; sticking a light-sensing chip onto said substrate with an adhesive layer; electrically connecting said light-sensing chip to said metallization traces with multiple bond wires in a wire-bonding procedure; cleaning pollutants on said substrate; and installing a light transparent cover having a cavity to said substrate with a glue material, with said light-sensing chip contained inside said cavity and enveloped by said light transparent cover, wherein said light transparent cover has at least one via-hole, said at least one-via hole balancing gas pressures inside and outside said light transparent cover when said glue material is being hardened for joining said light transparent cover with said substrate; after said glue material has been hardened, another glue is filled into said via-holes and hardened lest external humidity penetrate into said light transparent cover.
