  • Patent number: 8969197
    Abstract: A structure with improved electromigration resistance and methods for making the same. A structure having improved electromigration resistance includes a bulk interconnect having a dual layer cap and a dielectric capping layer. The dual layer cap includes a bottom metallic portion and a top metal oxide portion. Preferably the metal oxide portion is MnO or MnSiO and the metallic portion is Mn or CuMn. The structure is created by doping the interconnect with an impurity (Mn in the preferred embodiment), and then creating lattice defects at a top portion of the interconnect. The defects drive increased impurity migration to the top surface of the interconnect. When the dielectric capping layer is formed, a portion reacts with the segregated impurities, thus forming the dual layer cap on the interconnect. Lattice defects at the Cu surface can be created by plasma treatment, ion implantation, a compressive film, or other means.

  • Publication number: 20120282769
    Abstract: Methods of forming integrated circuit devices include forming an electrically conductive layer containing silicon on a substrate and forming a mask pattern on the electrically conductive layer. The electrically conductive layer is selectively etched to define a first sidewall thereon, using the mask pattern as an etching mask. The first sidewall of the electrically conductive layer may be exposed to a nitrogen plasma to thereby form a first silicon nitride layer on the first sidewall. The electrically conductive layer is then selectively etched again to expose a second sidewall thereon that is free of the first silicon nitride layer. The mask pattern may be used again as an etching mask during this second step of selectively etching the electrically conductive layer.

  • Publication number: 20120098141
    Abstract: A semiconductor device and a method for forming the same are disclosed. The semiconductor device includes a semiconductor substrate including an active region defined by a device isolation film, a bit line contact plug that is coupled to the active region and that includes a first ion implantation region buried in a first inner void, and a storage node contact plug that is coupled to the active region and includes a second ion implantation region buried in a second inner void. Although the semiconductor device is highly integrated, a contact plug is buried to prevent formation of a void, so that increase in contact plug resistance is prevented, resulting in improved semiconductor device characteristics.

  • Publication number: 20120088365
    Abstract: By moderately introducing defects into a highly conductive material, such as copper, the resistance versus temperature behavior may be significantly modified so that enhanced electromigration behavior and/or electrical performance may be obtained in metallization structures of advanced semiconductor devices. The defect-related portion of the resistance may be moderately increased so as to change the slope of the resistance versus temperature curve, thereby allowing the incorporation of impurity atoms for enhancing the electromigration endurance while not unduly increasing the overall resistance at the operating temperature or even reducing the corresponding resistance at the specified operating temperature. Thus, by appropriately designing the electrical resistance for a target operating temperature, both the electromigration behavior and the electrical performance may be enhanced.

  • Patent number: 8039395
    Abstract: An alloy forming dopant material is deposited prior to the formation of a copper line, for instance by incorporating the dopant material into the barrier layer, which is then driven into the vicinity of a weak interface by means of a heat treatment. As indicated by corresponding investigations, the dopant material is substantially transported to the weak interface through grain boundary regions rather than through the bulk copper material (copper grains), thereby enabling moderately high alloy concentrations in the vicinity of the interface while maintaining a relatively low overall concentration within the grains. The alloy at the interface reduces electromigration along the interface.
