Abstract:
A method for determining resistance changes induced by electromigration in a conductive pattern, comprising at least one sequence of the steps of:applying substantially simultaneous a first unidirectional current to a first conductive pattern and a second alternating symmetric current to a second conductive pattern, said first and said second conductive pattern being essentially identical and placed on the same substrate, said first current and said second current thereby leading to substantially the same amount of power dissipation in said first conductive structure and said second conductive structure respectively;measuring the resistance changes of said first conductive pattern and said second conductive pattern by applying substantially simultaneous a third alternating current to said first conductive pattern and a fourth alternating current to said second conductive pattern, said third current and said fourth current thereby leading to substantially the same amount of power dissipation in said first conductive structure and said second conductive structure respectively.
