    Abstract: A process for preparing a surface of a lower level metal structure, exposed at the bottom of a sub-micron diameter opening, to allow a low resistance interface to be obtained when overlaid with an upper level metal structure, has been developed. A disposable, capping insulator layer is first deposited on the composite insulator layer in which the sub-micron diameter opening will be defined in, to protect underlying components of the composite insulator from a subsequent metal pre-metal procedure. After anisotropically defining the sub-micron diameter opening in the capping insulator, and composite insulator layers, and after removal of the defining photoresist shape, an argon sputtering procedure is used to remove native oxide from the surface of the lower level metal structure. In addition to native oxide removal the argon sputtering procedure, featuring a negative DC bias applied to the substrate, also removes the capping insulator layer from the top surface of the composite insulator layer. An in situ metal deposition then allows a clean interface to result between the overlying metal layer, and the underlying plasma treated, metal surface.

    Abstract: An interconnect structure for a semiconductor device and its method of manufacture is provided. The interconnect structure includes a multi-layer structure having one or more stress-relief layers. In an embodiment, stress-relief layers are positioned between layers of electroplated copper or other conductive material. The stress-relief layer counteracts stress induced by the conductive material and helps prevent or reduce a pull-back void. For an interconnect structure using electroplated copper, the stress-relief layer may be formed by temporarily reducing the electroplating current, thereby causing a thin film of copper having a larger grain size to be formed between other layers of copper. The larger grain size typically exhibits more of a compressive stress than copper with a smaller grain size. The stress relief layer may also be formed of other materials, such as SIP-Cu, Ta, SiC, or the like.

    Abstract: Via structure and process flow for interconnection in a semiconductor product. A bottom metal layer is provided to represent a connection layer in the semiconductor product. An isolation layer on the bottom metal layer comprises a via hole exposing a portion of the bottom metal layer. The via hole comprises a sidewall and a bottom. A first barrier metal layer is disposed on the sidewall of the via hole, but not on the bottom of the via hole. A metal under-layer is formed on the bottom of the via hole and on the first barrier metal layer. A second barrier metal layer is formed on the metal under-layer. A metal fill layer fills the via hole. A lattice mismatch between the metal under-layer and the second barrier metal layer is less than about 5%.

    Abstract: A novel test device and method for calibrating the alignment of a laser beam emitted from a laser metrology tool with respect to a target area on a substrate. The test device includes a laser-sensitive material having a calibration pattern that includes a target point. When the tool is properly adjusted, the laser beam strikes the target point and is released to production. If the laser beam misses the target point, the tool is re-adjusted and re-tested until the laser beam strikes the target point.
