ABSTRACT:
A circuit board structure of integrated optoelectronic components is composed of: a carrying board with at least one through opening; a first optoelectronic component accommodated in the through opening, which has an active surface and a non-active surface. A dielectric layer, a circuit layer and build-up layers are successively formed on the active surface of the optoelectronic component and the carrying board. A first opening penetrates the dielectric layer and the circuit layer while a second opening penetrates the build-up layers. The present invention provides that the circuit layer is directly formed on the surface of the first optoelectronic component so that the registration between the circuit layer and the electrode pads of the optoelectronic component is improved. Moreover, the optical transmission component for transmitting signal is integrated in the build-up circuit layer. Thus, the cost is reduced, the production is improved and the volume is shrunken.
