US Patent 11347001 Semiconductor structure and method of fabricating the same

A structure adapted to optical coupled to an optical fiber includes a photoelectric integrated circuit die, an electric integrated circuit die, a waveguide die and an insulating encapsulant. The electric integrated circuit die is over and electrically connected to the photoelectric integrated circuit die. The waveguide die is over and optically coupled to the photoelectric integrated circuit die, wherein the waveguide die includes a plurality of semiconductor pillar portions extending from the optical fiber to the photoelectric integrated circuit die. The insulating encapsulant laterally encapsulates the electric integrated circuit die and the waveguide die.
