    摘要: An interconnect structure of a semiconductor device designed for reduced intralevel and interlevel capacitance, and includes a lower metal layer and an upper metal layer and an insulating layer interposed between metal layers. Each of the lower metal layer and upper metal layer include a plurality of conductive lines spaced apart and extending within a low-k dielectric material. A plurality of metal-filled vias interconnects the conductive lines of the lower metal layer to the conductive lines of the upper metal layer. The insulating layer comprises also comprises a low-k dielectric material disposed between the adjacent metal-filled vias. Openings, having been etched in the low-k dielectric material between the conductive lines of the upper and lower metal layers, and the metal-filled vias, an ultra-low k material is deposited within the openings. The integration of the ultra-low k and low-d dielectric materials reduces the overall capacitance of the structure to enhance performance.

    摘要: A method for dry etching a material deposited on semiconductor device is performed by chemically reacting the material with an etchant gas. The etching process is conducted in a reaction chamber at a predetermined temperature and predetermined pressure within the reaction chamber and without the need of generating a plasma within the chamber or applying an electrical bias to the semiconductor device. A sufficient amount of gas is introduced into the reaction chamber to selectively remove the material from the semiconductor device.

    摘要: A method for treating an effluent gas from a semiconductor processing system includes the steps of exhausting the effluent gas from a processing chamber, and catalytically treating the effluent gas with the at least one mixed metal oxide. The effluent gas includes unconsumed process gasses introduced during semiconductor processing operations, such as during chemical vapor deposition (CVD) and plasma-reactive ion etching. The mixed metal oxide may include a hetero bi-metal oxide, a hetero tri-metal oxide, or a perovskite. A hetero bi-metal oxide includes LaCoO3 and LaMnO3, for example, and a hetero tri-metal oxide includes (LaxPr1−x)CoO3 and (LaxPr1−x)MnO3, for example. The effluent gas may include at least carbon monoxide and/or ozone. Thus, catalytically treating the effluent gas preferably includes the catalytically converting carbon monoxide to carbon dioxide and/or ozone to oxygen. With the effluent gas being treated by the catalytic converter prior to being released into the atmosphere, undesirable gases, such as carbon monoxide and unreacted ozone are efficiently converted into non-harmful carbon dioxide and oxygen.

    摘要: A titanium nitride barrier within an integrated contact structure is formed as multi-layered stack. The multi-layering of the titanium nitride thus provides improved junction integrity since the multi-layer structure exhibits improved mechanical stability when compared to conventional single layer arrangements. The multi-layer titanium nitride barrier may be used as either a conventional interconnect metallization or as a nucleation structure within a tungsten plug. The multi-layer structure may be formed to include an overall thickness less than a conventional single layer, yet provide for improved stress accommodation, resulting in eliminating micro-cracks within the titanium nitride (and as a result eliminating the un-wanted diffusion of aluminum or tungsten precursors through the titanium nitride).
