  • Patent number: 11984342
    Abstract: A method includes forming a first polymer layer to cover a metal pad of a wafer, and patterning the first polymer layer to form a first opening. A first sidewall of the first polymer layer exposed to the first opening has a first tilt angle where the first sidewall is in contact with the metal pad. The method further includes forming a metal pillar in the first opening, sawing the wafer to generate a device die, encapsulating the device die in an encapsulating material, performing a planarization to reveal the metal pillar, forming a second polymer layer over the encapsulating material and the device die, and patterning the second polymer layer to form a second opening. The metal pillar is exposed through the second opening. A second sidewall of the second polymer layer exposed to the second opening has a second tilt angle greater than the first tilt angle.

  • Patent number: 11948881
    Abstract: A semiconductor structure includes a die, a molding surrounding the die, a first dielectric layer disposed over the die and the molding, and a second dielectric layer disposed between the first dielectric layer and the die, and between the first dielectric layer and the molding. A material content ratio in the first dielectric layer is substantially greater than that in the second dielectric layer. In some embodiments, the material content ratio substantially inversely affects a mechanical strength of the first dielectric layer and the second dielectric layer.
