Zusammenfassung:A manufacturing method of a semiconductor structure includes at least the following steps. A semiconductor device having a first surface and a second surface opposite to the first surface is provided. A plurality of through semiconductor vias (TSV) embedded in the semiconductor device is formed. A first seal ring is formed over the first surface of the semiconductor device. The first seal ring is adjacent to edges of the first surface and is physically in contact with the TSVs. A second seal ring is formed over the second surface of the semiconductor device. The second seal ring is adjacent to edges of the second surface and is physically in contact with the TSVs.
