<p>A process is described for the fabrication of submicron interconnect structures for integrated circuit chips. Void-free and seamless conductors are obtained by electroplating Cu from baths that contain additives and are conventionally used to deposit level, bright, ductile, and low-stress Cu metal. The capability of this method to superfill features without leaving voids or seams is unique and superior to that of other deposition approaches.</p> |
