Packaging silicon on silicon multichip modules

摘要

The specification describes interconnection assemblies for silicon-on-silicon multichip modules. The silicon-on-silicon MCMs are mounted on epoxy/glass laminates which have a coefficient of thermal expansion (CTE) that essentially matches the CTE of silicon. In the preferred embodiment the assembly is a PC card with card edge connectors, i.e. without fixed solder interlevel interconnections, so that the CTE of the epoxy laminate comprising the card can be modified without regard to potential mismatch with a mother board.
