Patent ID: 7450793

Claim:
A method for fabricating a semiconductor device integrated with opto-electric component, comprising the steps of: providing a wafer with a plurality of first optical transmitter/receiver components, each of the first optical transmitter/receiver components having an active surface and an opposite non-active surface, wherein a plurality of connecting pads and an optical active area are formed on the active surface; forming a dielectric layer on the wafer; forming a circuit layer on the dielectric layer, wherein the circuit layer is electrically connected to the connecting pads of the first optical transmitter/receiver components through electrical conductive vias formed in the dielectric layer and disposed onto the connecting pads, and an opening is formed in the dielectric layer at a position corresponding to the optical active area on the active surface of each of the optical transmitter/receiver components to expose the optical active area; forming an insulating layer on the circuit layer and the dielectric layer, wherein the insulating layer is formed with openings to expose electrically connecting pads in the circuit layer; performing a routing process on the wafer, to form a plurality of integrated devices with the first optical transmitter/receiver components and circuit structures, wherein the size of the dielectric layer formed on each first optical transmitter/receiver component is equal to the size of each first optical transmitter/receiver component, and the size of the insulating layer formed on the circuit layer and the dielectric layer is equal to the size of each first optical transmitter/receiver component; and mounting a second optical transmitter/receiver component on the electrically connecting pads exposed from the insulating layer, wherein an optical active area of the second optical transmitter/receiver component corresponds to one of the openings penetrating the dielectric layer and faces the optical active area of a corresponding one of the first optical transmitter/receiver components, to form a plurality of integrated devices with the first and second optical transmitter/receiver components.
