    Abstract: Provided is a method of manufacturing a semiconductor device having a first region, in which a capacitance component is a dominant cause of a RC delay, and a second region, in which a resistance component is a dominant cause of a RC delay. The method comprises performing a first etching process to an insulating layer formed on a semiconductor substrate, so that a first trench having a first thickness and a second trench having the first thickness are formed in the first region and the second region, respectively; performing a second etching process to the second trench, so that a third trench having a second thickness thicker than the first thickness is formed in the second region; filling the first trench and the third trench with a metal layer; and removing portions of the metal layer, so that a first metal interconnection and a second metal interconnection are formed inside of the first trench and the third trench, respectively.

    Abstract: A method of forming damascene wiring without dishing and erosion employs a dummy layer to slow or delay polishing in selected regions and thereby prevent dishing and erosion of the damascene wiring. The dummy layer is above wide damascene regions and areas containing closely packed damascene regions. Therefore, non-uniform sheet resistance of the damascene metal wiring and electro-migration due to an increase in the local current density of the metal wiring can be prevented.

    Abstract: A metal interconnection structure includes a lower metal interconnection layer disposed in a first inter-layer dielectric layer. An inter-metal dielectric layer having a via contact hole that exposes a portion of surface of the lower metal layer pattern is disposed on the first inter-layer dielectric layer and the lower metal layer pattern. A second inter-layer dielectric layer having a trench that exposes the via contact hole is formed on the inter-metal dielectric layer. A barrier metal layer is formed on a vertical surface of the via contact and the exposed surface of the second lower metal interconnection layer pattern. A first upper metal interconnection layer pattern is disposed on the barrier metal layer, thereby filling the via contact hole and a portion of the trench. A void diffusion barrier layer is disposed on the first metal interconnection layer pattern and a second upper metal interconnection layer pattern is disposed on the void diffusion barrier layer to completely fill the trench.
