Abstract: A semiconductor device is fabricated by forming a lower conductor in a first interlayer dielectric film. A second interlayer dielectric film is formed on the lower conductor and the first interlayer dielectric film. A first hard mask pattern is formed on the second interlayer dielectric film. The first mask pattern has a first opening extending in a first direction. A planarization layer is formed on the first hard mask pattern. A mask pattern is formed on the planarization layer. The mask pattern has a second opening extending in a second direction perpendicular to the first direction. The lower conductor is positioned under an region where the first opening and the second opening overlap. A via hole and a trench connected to the via hole is formed using the first hard mask pattern and the mask pattern. The via hole exposes an upper surface of the lower conductor.
