Abstract
Embodiments of the present invention provide methods to reduce the copper line roughness for increased electrical conductivity in narrow interconnects having a width of less than 100 nm. These methods reduce the copper line roughness by first smoothing the surface on which the copper lines are formed by performing a short electrochemical etch of the surface. The electrical conductivity of the interconnects is increased by reducing the copper line roughness that in turn reduces the resistivity of the copper lines.
