  • Patent number: 6344125
    Abstract: A process for the electrolytic deposition of a metal, preferably copper or an alloy of copper, directly onto a barrier layer coated on a dielectric layer. The process is advantageous because it electrolytically deposits metal in a pattern that is either the duplicate of a first conductive pattern under the dielectric or the inverse image of the first conductive pattern, depending on the first conductive pattern shape. Thus, metal is deposited on the barrier layer duplicating a first conductive pattern under the dielectric layer when the first pattern is a serpentine pattern and the metal deposits in the spaces between the conductive lines of a first conductive pattern of a discrete passive element such as a spiral.
