Beschreibung
Zusammenfassung:	A method for manufacturing a semiconductor structure is provided. The method includes the operations as follows. A first substrate having a top surface is received. A semiconductor layer is formed over the first substrate. A cavity is formed at the top surface of the semiconductor layer. A second substrate is bonded over the first substrate to cover the semiconductor layer. The second substrate has a through hole connected to the cavity of the semiconductor layer. A eutectic sealing structure is formed on the second substrate to cover the through hole. The eutectic sealing structure includes a first metal layer and a second metal layer eutectically bonded on the first metal layer.
