Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 13:
14. A package structure, comprising:
a circuit board comprising an optical waveguide;
a first fanout package disposed over the circuit board, the first fanout package comprising a first photoelectric integrated circuit die, a first insulating encapsulant laterally encapsulating the first photoelectric integrated circuit die, and a first redistribution circuit layer covering the first photoelectric integrated circuit die and the first insulating encapsulant, the first photoelectric integrated circuit die being optically coupled to the optical waveguide of the circuit board, wherein the first redistribution circuit layer comprises a first optical window located between a first end of the optical waveguide and the first photoelectric integrated circuit die; and
a second fanout package disposed over the circuit board, the second fanout package comprising a second photoelectric integrated circuit die optically coupled to the optical waveguide of the circuit board.
