Abstract: A protective barrier layer, formed of a material such as titanium or titanium nitride for which removal by chemical mechanical polishing (CMP) is primarily mechanical rather than primarily chemical, formed on a conformal tungsten layer. During subsequent CMP to pattern the tungsten layer, upper topological regions of the protective barrier layer (such as those overlying interlevel dielectric regions) are removed first, exposing the tungsten under those regions to removal, while protective barrier layer regions over lower topological regions (such as openings within the interlevel dielectric) remain to prevent chemical attack of underlying tungsten.

Abstract: A metal interconnection of a semiconductor device, formed using a damascene process, has large grains and yet a smooth surface. First, a barrier layer and a metal layer are sequentially formed in an opening in an interlayer dielectric layer. A CMP process is carried out on the metal layer to form a metal interconnection remaining within the opening. Then, the metal interconnection is treated with plasma. The plasma treatment creates compressive stress in the metal interconnection, which stress produces hillocks at the surface of the metal interconnection. In addition, the plasma treatment process causes grains of the metal to grow, especially when the design rule is small, to thereby decrease the resistivity of the metal interconnection. The hillocks are then removed by a CMP process aimed at polishing the portion of the barrier layer that extends over the upper surface of the interlayer dielectric layer. Finally, a capping insulating layer is formed.
