Abstract:
A package structure including a first semiconductor die, a second semiconductor die, a molding compound, an interconnect structure, first conductive features, through insulator vias, an insulating encapsulant and a redistribution layer is provided. The molding compound is encapsulating the first semiconductor die and the second semiconductor die. The interconnect structure is disposed on the molding compound and electrically connecting the first semiconductor die to the second semiconductor die. The first conductive features are electrically connected to the first semiconductor die and the second semiconductor die, wherein each of the first conductive features has a recessed portion. The through insulator vias are disposed on the recessed portion of the first conductive features and electrically connected to the first and second semiconductor die. The insulating encapsulant is encapsulating the interconnect structure and the through insulator vias. The redistribution layer is disposed on the insulating encapsulant and over the interconnect structure.

Claim (Index 15):
A method of fabricating a package structure, comprising:\n providing a carrier; disposing a first semiconductor die having a plurality of conductive vias on the carrier; disposing a second semiconductor die having a plurality of conductive vias on the carrier adjacent to the first semiconductor die; forming a molding compound encapsulating the first semiconductor die and the second semiconductor die; forming a dielectric layer on the molding compound and patterning the dielectric layer to form a plurality of first openings and a plurality of second openings, wherein the plurality of first openings surround the plurality of second openings, and a width of the plurality of first openings is greater than a width of the plurality of second openings; forming a plurality of first conductive features in the plurality of first openings, wherein the plurality of first conductive features is formed with flank portions and a recessed portion joining the flank portions, and the recessed portion being physically connected to the plurality of conductive vias of the first semiconductor die and the plurality of conductive vias of the second semiconductor die; forming a plurality of second conductive features in the plurality of second openings, wherein the plurality of second conductive features is physically connected to the plurality of conductive vias of the first semiconductor die and the plurality of conductive vias of the second semiconductor die; forming a plurality of through insulator vias on the recessed portion of the plurality of first conductive features, the plurality of through insulator vias being electrically connected to the first semiconductor die and the second semiconductor die; disposing an interconnect structure on the plurality of second conductive features and electrically connecting the first semiconductor die to the second semiconductor die; forming an insulating encapsulant encapsulating the interconnect structure and the plurality of through insulator via, wherein the insulating encapsulant is separating the interconnection structure from the plurality of through insulator vias; forming a redistribution layer on the insulating encapsulant and over the interconnect structure, wherein the redistribution layer is electrically connected to the plurality of through insulator vias; and de-bonding the carrier.
