Abstract
A semiconductor device includes a substrate, a structured interlayer on the substrate and having defined edges, and a structured metallization on the structured interlayer and also having defined edges. Each defined edge of the structured interlayer neighbors one of the defined edges of the structured metallization and runs in the same direction as the neighboring defined edge of the structured metallization. Each defined edge of the structured interlayer extends beyond the neighboring defined edge of the structured metallization by at least 0.5 microns so that each defined edge of the structured metallization terminates before reaching the neighboring defined edge of the structured interlayer. The structured interlayer has a compressive residual stress at room temperature.
