  • Patent number: 12230593
    Abstract: A package structure is provided, including a substrate, a first passivation layer, a metallization layer, a second passivation layer, and a polymer layer. The first passivation layer is formed over the substrate. The metallization layer is conformally formed on the first passivation layer. The second passivation layer is conformally formed on the first passivation layer and the metallization layer. A step structure is formed on the top surface of the second passivation layer, and includes at least one lower part that is lower than the other parts of the step structure. The polymer layer is formed over the second passivation layer. A portion of the polymer layer extends into the lower part of the step structure to engage with the step structure.

  • Patent number: 11855007
    Abstract: A semiconductor structure includes a semiconductor device, a plurality of through semiconductor vias (TSV), a first seal ring, and a second seal ring. The TSVs are in the semiconductor device. Each of the TSVs has a first surface and a second surface opposite to the first surface. The first seal ring is located in proximity to an edge of the semiconductor structure and is physically connected to the first surface of each of the TSVs. The second seal ring is physically connected to the second surface of each of the TSVs.
