Abstract
A technique for estimating the reliability of multilayer metallization of integrated circuits at constant temperature has been implemented and tested. Statistical processing of the data has been carried out and the main reliability parameters of conductors have been calculated. The main types of failure, which commonly arise upon electromigration testing at constant temperature, have been demonstrated and analyzed.
