Abstract
A method of manufacturing an interconnection layer for a semiconductor device comprising the steps of forming a conductive pattern near a surface of a semiconductor substrate or on the surface of the semiconductor substrate, forming an insulation layer on a surface of the conductive pattern, forming grooves in the insulation layer exposing portions of the conductive pattern, forming a first barrier layer pattern on an upper surface of the insulation layer and on sidewalls and bottoms of each of the grooves, selectively forming a seed layer on portions of the first barrier layer pattern, selectively forming a copper interconnection layer on the first barrier layer pattern and the seed layer, and forming a second barrier layer on an upper surface and sides of the copper interconnection layer.
