US Patent 10522470 Package structure and method of fabricating the same

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.
