Claim:
1. A method for manufacturing a semiconductor device, comprising: providing a substrate, wherein the substrate has a first region and a second region; forming at least one sensor in the substrate of the first region; forming a dielectric layer on the substrate of the first region and the second region; forming at least one light pipe structure in the dielectric layer of the first region, wherein the light pipe structure corresponds to the sensor; forming at least one pad in the dielectric layer of the second region; forming a shielding layer on the dielectric layer, wherein the shielding layer surrounds the light pipe structure; and forming a protection layer on the shielding layer, wherein at least one pad opening is formed in the dielectric layer, the shielding layer and the protection layer above the pad for exposing a top surface of the corresponding pad.
