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

Claim 15:
16. A package structure, comprising:
an insulating encapsulation;
at least one semiconductor die, encapsulated in the insulating encapsulation;
a conductive paste, covering a backside of the at least one semiconductor die, wherein a portion of the conductive paste is between the insulating encapsulation and the at least one semiconductor die;
a waveguide structure, located aside and electrically coupled to the at least one semiconductor die and encapsulated in the insulating encapsulation;
antennas, disposed over the at least one semiconductor die, wherein the antennas are electrically connected to the waveguide structure in a manner of electrical coupling, and the antennas are electrically communicated with the at least one semiconductor die through the waveguide structure;
at least one isolation structure, disposed over the at least one semiconductor die, wherein the at least one isolation structure laterally separates apart the antennas, and the at least one isolation structure is electrically coupled to the at least one semiconductor die and is electrically isolated from the antennas; and
a plurality of conductive pillars, encapsulated in the insulating encapsulation next to the waveguide structure, and electrically connected to the at least one semiconductor die.
