Abstract
Normally and highly accelerated electromigration tests on Al-Cu lines of different widths are compared. It is shown that the use of the Blac k equation gives different extrapolated results depending on the range of stress conditions considered. It is concluded that for extrapolati ons it is safe to use the Black equation only in the case of normally accelerated stress conditions (temperatures in the range 158-240 degre es C and current densities between 1 and 2 MA/cm(2)) and when the extr acted value for the current density acceleration factor is 2.
