Abstract
Thermal degradation of a low-k organic dielectric material is avoided or limited in the proximity of a heat source such as a fusible element by overlaying the low-k material with a thermally conductive material and providing a low thermal resistance path from the thermally conductive material, possibly having a low modulus of elasticity, to a heat sink. The thermally conductive material thus provides crack-stop protection for further layers of an integrated circuit or interconnect structure above the fusible element by mechanical, chemical and thermal encapsulation of the heat source and low-k material.
