Abstract

Increases in cross-talk disturbance, signal delay and current density have a significant impact on the performance of integrated systems as the metal pitch continues to be scaled down. A metal, such as copper, which has high conductivity and high resistance to migration, will greatly alleviate these problems. A selective technique for the deposition of copper, such as electroless plating, is highly desirable because it circumvents the potential problem of dry etching copper and inherently planarizes the surface topography.
