Abstract:
A package structure including a semiconductor die, an insulating encapsulant, and a redistribution layer is provided. The semiconductor die includes a semiconductor substrate, a plurality of metallization layers disposed on the semiconductor substrate, and a passivation layer disposed on the plurality of metallization layers. The passivation layer has a first opening that partially expose a topmost layer of the plurality of metallization layers. The insulating encapsulant is encapsulating the semiconductor die. The redistribution layer includes at least a first dielectric layer and a first conductive layer stacked on the first dielectric layer. The first dielectric layer has a second opening that overlaps with the first opening, and a width ratio of the second opening to the first opening is in a range of 2.3:1 to 12:1. The first conductive layer is electrically connected to the topmost layer of the plurality of metallization layers through the first and second openings.

Claim (Index 16):
A method of fabricating a package structure, comprising:\n providing a carrier; forming a first redistribution layer having at least one conductive layer and a dielectric layer on the carrier; disposing a sensor die on the first redistribution layer, wherein the sensor die comprises a semiconductor substrate, a plurality of metallization layers disposed on the semiconductor substrate, and a passivation layer disposed on the plurality of metallization layers, wherein the passivation layer has a first opening that partially expose a topmost layer of the plurality of metallization layers; forming an insulating encapsulant encapsulating the sensor die, wherein a top surface of the insulating encapsulant is substantially coplanar with a top surface of the passivation layer having the first opening; forming a second redistribution layer on the sensor die and the insulating encapsulant, wherein the forming of the second redistribution layer comprises forming a first dielectric layer having a second opening that overlaps with the first opening, then forming a touch sensing electrode on the first dielectric layer, wherein a width of the second opening is greater than a width of the first opening, and the touch sensing electrode is electrically connected to the topmost layer of the plurality of metallization layers through the first opening and the second opening; debonding the carrier; and forming a plurality of conductive terminals on the first redistribution layer.
