Method for making camera modules and camera module made thereby

1. A method for making camera modules, comprising the steps of:

a) providing a wafer including an array of sensor chips;

b) mounting a plurality of lens assemblies on the sensor chips, respectively, thereby defining a plurality of intersecting spacing grooves among the lens assemblies;

c) mounting a cover layer over the lens assemblies and the spacing grooves, the cover layer including a plurality of light-transmissive holes corresponding to the lens assemblies and a plurality of spaced apart injecting holes communicated with the spacing grooves;

d) forming a substrate layer by filling in the spacing grooves with a resin material through the injecting holes; and

e) cutting the wafer, the cover layer, and the substrate layer along intersecting cutting lines each extending along one of the spacing grooves and each intervening the lens assemblies, wherein the substrate layer is divided into a plurality of barrels respectively surrounding the lens assemblies, and the cover layer is divided into a plurality of covers each of which has one of the light-transmissive holes and each of which is disposed over one of the barrels and one of the lens assemblies.

2. The method as claimed in claim 1 , further comprising mounting a surrounding wall on the wafer before the step d), the surrounding wall extending along the periphery of the wafer and surrounding the lens assemblies and the spacing grooves, wherein the resin material is injected into the surrounding wall and the spacing grooves in the step d).

3. The method as claimed in claim 1 , wherein the step d) is conducted by insert molding.

4. The method as claimed in claim 1 , further comprising a step of mounting a plurality of conductive blocks on the wafer opposite to the lens assemblies.
