Claim 15:
16. A method comprising:
forming a first interconnect structure comprising:
forming a plurality of vias on a first redistribution structure;
forming a plurality of interconnect devices on the first interconnect structure, wherein the interconnect devices are free of active devices, wherein each interconnect device respectively comprises a plurality of through-vias in a substrate;
encapsulating the plurality of vias and the plurality of interconnect devices; and
forming a second redistribution structure on the plurality of vias and on the plurality of interconnect devices, wherein the second redistribution structure is electrically coupled to the first redistribution structure;

connecting a photonic device to the second redistribution structure, wherein the photonic device comprises a waveguide; and
connecting a first semiconductor device to the second redistribution structure adjacent the photonic device.
