Patent ID: 8246795

Claim:
A method for fabricating a lens module, comprising: forming an IR-cut filter; forming a shading block on a part of a surface of the IR-cut filter; forming a blocking layer on the IR-cut filter and the shading block, the blocking layer comprising a first surrounding portion surrounding the IR-cut filter and a first protruding portion located in the shading block; forming an electromagnetic shielding layer on the blocking layer, the electromagnetic shielding layer comprising a second surrounding portion formed on the first surrounding portion and a second protruding portion formed on the first protruding portion; polishing the second protruding portion of the electromagnetic shielding layer and the first protruding portion of the blocking layer to expose the shading block; removing the shading block from the IR-cut filter to form an optical component, the optical component comprising an IR-cut filter portion formed by the IR-cut filter and a barrel portion cooperatively formed by the first surrounding portion and the second surrounding portion; mounting a lens in the barrel portion adjacent to the IR-cut filter portion; and packaging the holding portion of the optical component to a printed circuit board to form the lens module.
