Abstract

It is proposed to minimize cracks or tears occurring when glass- ceramic substrates used in semiconductor devices are sintered. The proposal suggests a better match of the thermal coefficient of expansion (TCE) of the contact sheet to the TCE of the substrate thereby reducing stresses at the interface.
