Beschreibung
Zusammenfassung:	A semiconductor structure is provided. The semiconductor structure includes a first substrate, a semiconductor layer, a second substrate, and a eutectic sealing structure. The semiconductor layer is over the first substrate. The semiconductor layer has a cavity at least partially through the semiconductor layer. The second substrate is over the semiconductor layer. The second substrate has a through hole. The eutectic sealing structure is on the second substrate and covers the through hole. The eutectic sealing structure comprises a first metal layer and a second metal layer eutectically bonded on the first metal layer. A method for manufacturing a semiconductor structure is also provided.
