    摘要: In a method for fabricating a semiconductor device, a substrate is provided including an interlayer dielectric layer and first and second hard mask patterns sequentially stacked thereon. A first trench is provided in the interlayer dielectric layer through the second hard mask pattern and the first hard mask pattern. A filler material is provided on the interlayer dielectric layer and the second hard mask pattern to fill the first trench. An upper portion of the second hard mask pattern is exposed by partially removing the filler material. The second hard mask pattern is removed, and remaining filler material is removed from the first trench. A wiring is formed by filling the first trench with a conductive material.
