Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. A method comprising:
placing an electronic die and a photonic die over a carrier;
encapsulating the electronic die and the photonic die in an encapsulant;
planarizing the encapsulant, so that an electrical connector in the electronic die is exposed, and a through-via that extends into a semiconductor substrate of the photonic die is exposed;
forming a redistribution structure over the encapsulant, the electronic die, and the photonic die, wherein a first redistribution line in the redistribution structure is joined to the electrical connector in the electronic die, and a second redistribution line in the redistribution structure is joined to the through-via in the photonic die; and
attaching an optical coupler to the photonic die, wherein an optical fiber attached to the optical coupler is configured to optically couple to the photonic die.
