    摘要: Example embodiments provide a semiconductor device and a method of forming the same. According to the method, a capping insulation pattern may be formed to cover the top surface of a filling insulation pattern in a trench. The capping insulation pattern may have an etch selectivity according to the filling insulation pattern. As a result, the likelihood that the filling insulation layer may be etched by various cleaning processes and the process removing the buffer insulation pattern may be reduced or prevented.

    摘要: A method of forming a via contact structure using a dual damascene process is disclosed. According to one embodiment a sacrificial layer is formed on an insulating interlayer during the formation of a preliminary via hole. The sacrificial layer has the same composition as a layer filling the preliminary via hole in a subsequent trench formation process. The sacrificial layer and the layer filling the preliminary via hole are simultaneously removed after the trench formation process is carried out. According to another embodiment, a thin capping oxide layer is formed on an insulating interlayer during the formation of a preliminary via hole. The thin capping oxide layer is removed together with a sacrificial layer after a trench formation process is carried out.

    摘要: The present invention discloses a method of fabricating interconnection lines for a semiconductor device. The method includes forming an interlayer insulating layer on a semiconductor substrate. A via hole is formed through the interlayer insulating layer. A via filling material is formed to fill the via hole. A photoresist pattern is formed on the via filling material. The via filling material and the interlayer insulating layer are anisotropically etched using the photoresist pattern as an etch mask to form a trench. A residual portion of the via filling material is removed using two wet etch processes. After removing the residual portion of the via filling material, a conductive layer pattern is formed in the via hole and the trench.
