    摘要: A method of fabricating a semiconductor device, the method including forming on a substrate a transistor that includes a gate electrode and a source and drain region, forming an interlayer insulating film on the transistor, forming a contact hole in the interlayer insulating film to expose a top surface of the source and drain region, and a thin film is formed at an interface between the contact hole and the exposed top surface of the source and drain region. The method further including selectively removing at least a portion of the thin film by performing an etching process in a non-plasma atmosphere, forming an ohmic contact film on the source and drain region where at least a portion of the thin film was selectively removed, and forming a contact plug by filling the contact hole with a conductive material.

    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.
