An edge seal around the periphery of an integrated circuit device which
environmentally protects the copper circuitry from cracks that may form
in the low-k interlevel dielectric during dicing. The edge seal
essentially constitutes a dielectric wall between the copper circuitry
and the low-k interlevel dielectric near the periphery of the integrated
circuit device. The dielectric wall is of a different material than the
low-k interlevel dielectric.
