Abstract

A method for forming a semiconductor structure includes receiving a die; forming a dielectric layer to surround the die; removing a portion of the dielectric layer to form a first recess; disposing a first light blocking layer within the first recess; applying a dielectric paste over the first light blocking layer; removing a portion of the dielectric paste to form a second recess; disposing a second light blocking layer within the second recess; disposing a photoelectric device over the first light blocking layer and the second light blocking layer; forming a redistribution layer over the die, the dielectric layer and the photoelectric device; removing a portion of the redistribution layer to form a third recess over the photoelectric device; and coupling a light-conducting member to the photoelectric device through the third recess; wherein the second light blocking layer is separated from the first light blocking layer and the photoelectric device.
