Abstract: In one embodiment, a method of forming metal interconnects uses a direct metal etch approach to form and fill the metal gap. The method may include directly etching a metal layer to form metal patterns. The metal patterns may be spaced apart from one another by recesses. A dielectric spacer may be formed extending along the sidewalls of each of the recesses. The recesses may be filled with a conductive material to form a second set of metal patterns. By directly etching the metal film, the technique allows for reduced line width roughness. The disclosed structure may have the advantages of increased reliability, better RC performance and reduced parasitic capacitance.
