Patent ID: 10930586

Abstract:
An integrated fan-out package includes a die, an insulating encapsulation, a redistribution circuit structure, conductive terminals, and barrier layers. The insulating encapsulation encapsulates the die. The redistribution circuit structure includes a first redistribution conductive layer on the insulating encapsulation, a first inter-dielectric layer covering the first redistribution conductive layer, and a second redistribution conductive layer on the first inter-dielectric layer. The first redistribution conductive layer includes conductive through vias extending from a first surface of the insulating encapsulation to a second surface of the insulating encapsulation. The first inter-dielectric layer includes contact openings, portions of the second redistribution conductive layer filled in the contact openings are in contact with the first redistribution conductive layer and offset from the conductive through vias. The conductive terminals are disposed over the second surface of the insulating encapsulation. The barrier layers respectively are disposed between the conductive through vias and the conductive terminals.
