Abstract: A semiconductor device includes an insulating interlayer disposed on a substrate, a first protection pattern, a first barrier pattern, a first adhesion pattern, and a first conductive pattern. The insulating interlayer includes a via hole and a first trench. The via hole extends through a lower portion of the insulating interlayer. The first trench is connected to the via hole and extends through an upper portion of the insulating interlayer. The first protection pattern covers a lower surface and sidewalls of the via hole and a portion of a lower surface and a lower sidewall of the first trench, and includes a conductive material. The first barrier pattern covers the protection pattern and an upper sidewall of the first trench. The first adhesion pattern covers the first barrier pattern.

Abstract: In a method of forming a wiring structure, a lower structure is formed on a substrate. An insulating interlayer is formed on the lower structure. The insulating interlayer is partially removed to form at least one via hole and a dummy via hole. An upper portion of the insulating interlayer is partially removed to form a trench connecting the via hole and the dummy via hole. A first metal layer filling the via hole and the dummy via hole is formed. A second metal layer filling the trench is formed on the first metal layer.
