Classification: CPC H | IPC H

Claim 0:
1. A semiconductor structure comprising:
a semiconductor device;
a heat-spreading mount;
a bonding joint joining the semiconductor device and the heat-spreading mount, wherein the bonding joint includes a sandwich bonding structure, and the sandwich bonding structure includes:
a first Ag—In solid solution layer in contact with the semiconductor device;
a second Ag—In solid solution layer in contact with the heat-spreading mount; and
an Ag2In IMC (intermetallics compound) layer sandwiched by the first Ag—In solid solution layer and the second Ag—In solid solution layer, wherein a thickness of the Ag2In IMC layer is larger than a thickness of the first Ag—In solid solution layer and larger than a thickness of the second Ag—In solid solution layer.
