    摘要: A metal resistor and resistor material and method of forming the metal resistor are disclosed. The metal resistor may include an infused metal selected from the group consisting of: copper (Cu) infused with at least one of silicon (Si), nitrogen (N2), carbon (C), tantalum (Ta), titanium (Ti) and tungsten (W), and aluminum infused with at least one of silicon (Si), nitrogen (N2), carbon (C), tantalum (Ta), titanium (Ti) and tungsten (W). The method is less complex than conventional processes, allows control of the resistance by the amount of infusion material infused, and is compatible with conventional BEOL processes.

    摘要: An interconnect structure in which the electromigration resistance thereof is improved without introducing a gouging feature within the interconnect structure is provided. The interconnect structure includes a metallic interfacial layer that is at least horizontally present at the bottom of an opening located within a second dielectric material that is located atop a first dielectric material that includes a first conductive material embedded therein. The metallic interfacial layer does not form an alloy with an underlying conductive material that is embedded within the first dielectric material. In some embodiments of the present invention, the metallic interfacial layer is also present on exposed sidewalls of the second dielectric material that is located atop the first dielectric material. Atop the metallic interfacial layer there is present a diffusion barrier liner. In some embodiments, the diffusion barrier liner includes a lower layer of a metallic nitride and an upper layer of a metal. In accordance with the present invention, the metallic interfacial layer also does not form an alloy with any portion of the diffusion barrier liner.

    摘要: Semiconductor wiring structures including a dielectric layer having a metal wiring line therein, a via extending downwardly from the metal wiring line, a metal cap layer over the metal wiring line, and a local dielectric cap positioned within a portion of the metal cap layer and in contact with the metal wiring line and a related method are disclosed. The local dielectric cap represents an intentionally created weak point in the metal wiring line of a dual-damascene interconnect, which induces electromigration (EM) voiding in the line, rather than at the bottom of a via extending downwardly from the metal wiring line. Since the critical void size in line fails, especially with metal cap layer (liner) redundancy, is much larger than that in via fails, the EM lifetime can be significantly increased.

    摘要: The invention predicts premature dielectric breakdown in a semiconductor. At least one dielectric breakdown mode is calculated for the semiconductor wafer. If a one mode is calculated, premature dielectric breakdown will be associated with any semiconductor with a breakdown voltage less than a predetermined standard deviation of a plurality of breakdown voltages within said calculated mode. If multiple modes are calculated, the mode that most accurately represents dielectric breakdown for the semiconductor wafer is determined and premature dielectric breakdown will be associated with any semiconductor with a breakdown voltage less than a predetermined standard of the calculated mode that most accurately represents dielectric breakdown for the semiconductor wafer.
