Abstract

See full text

A microelectronic assembly including elements such as a semiconductor chip and substrate has electrical connections between the elements incorporating fusible conductive metal masses. The fusible masses are surrounded and contained by a compliant material such as an elastomer or gel. The fusible material may melt during operation or processing of the device to relieve thermal cycling stress in the electrical connections.
