Patent attributes
A semiconductor interconnection comprises a semiconductor device, a substrate adjacent the semiconductor device, and a plurality of spring contacts on the semiconductor device or the substrate. A plurality of solder connections are on the opposite semiconductor device or substrate. Each spring contact comprises a contact surface and a conductive material on the contact surface. Upon assembly of the semiconductor device and the substrate, the conductive material on the plurality of spring contacts makes contact with each of the plurality of solder connections. The conductive material is in a liquid state at manufacturing or operating temperatures of the semiconductor device. Thus, the conductive material could be a solid at room temperature and transition to a liquid state at the semiconductor's manufacturing or operating temperatures.
