Abstract:
A test structure used to determine reliability performance includes a patterned metallization structure having multiple interfaces, which provide stress risers. A dielectric material surrounds the metallization structure, where a mismatch in coefficients of thermal expansion (CTE) between the metallization structure and the surrounding dielectric material exist such that a thermal strain value is provided to cause failures under given stress conditions as a result of CTE mismatch to provide a yield indicative of reliability for a manufacturing design.
