  • Abstract
    This paper is to study the influence of Cu surface clean process on stressvoiding and electromigration of Cu dual damascene metallization. A superior Cu pre-cleaning process condition is developed to improve Cu stress-induced voiding (SIV) and electromigration (EM). Higher pre-clean bias-power and shorter pre-clean time demonstrate remarkable low via resistance and excellent Cu reliability performance.
