Copper wire interconnect reliability evaluation using in-situ High Temperature Storage Life (HTSL) tests
A four point resistance method was used to monitor the contact resistance of the CuAl. The data was analysed by deriving the corroded area from the resistance values. The method was applied to epoxy moulding compounds to compare their reliability performance. A model proposed earlier, was validated by this in-situ data. The method can be used for fast screening of new methods.
