    摘要: A method of layer formation on a substrate with high aspect ratio features is disclosed. The layer is formed from a gas mixture comprising one or more process gases and one or more etch species. The one or more process gases react to deposit a material layer on the substrate. In conjunction with the material layer deposition, the etch species selectively remove portions of the deposited material layer adjacent to high aspect ratio feature openings, filling such features in a void-free and/or seam-free manner. The material layer may be deposited on the substrate using physical vapor deposition (PVD) and/or chemical vapor deposition (CVD) techniques.

    摘要: The present invention provides a method and apparatus for forming reliable interconnects in which the overlap of the line over the plug or via is minimized or eliminated. In one aspect, a barrier plug comprised of a conductive material, such as tungsten, is deposited over the via to provide an etch stop during line etching and to prevent diffusion of the metal, such as copper, into the surrounding dielectric material if the line is misaligned over the via. Additionally, the barrier plug prevents an overall reduction in resistance of the interconnect and enables reactive ion etching to be employed to form the metal line. In another aspect, reactive ion etching techniques are employed to selectively etch the metal line and the barrier layer to provide a controlled etching process which exhibits selectivity for the metal line, then the barrier and then the via or plug.
