Abstract
Solder interconnection for forming connections between an integrated semiconductor device and a carrier substrate is provided. Located on the carrier substrate are electrodes and located between the electrodes and integrated semiconductor device are solder connections that have a relatively low melting point such that when the device is in operation, the solder connection will liquify thereby permitting expansion compensation between the substrate and semiconductor device.
