    摘要: A polishing process in a semiconductor device fabrication process employs a polishing composition in which a gaseous phase is created within the polishing composition. During a polishing process, the gaseous phase dynamically responds to changes in the surface profile of the material undergoing removal by chemical and abrasive action during polishing. The inert gas bubble density dynamically increases in proximity to surface region of the substrate being polished that are prone to dishing and erosion. The increased inert gas bubble density operates to reduce the polish removal rate relative to other regions of the substrate. The dynamic action of the gaseous phase within the polishing composition functions to selectively reduce the localized polish removal rate such that a uniformly smooth and flat polished surface is obtained that is independent of the influence of pattern density during the polishing process.

    摘要: The circuit structure includes at least two generally parallel conductor structures, and a plurality of substantially horizontal layers of layer dielectric material interspersed with substantially horizontally extending relatively low dielectric constant (low-k) volumes. The substantially horizontal layers and the substantially horizontally extending volumes are generally interposed between the at least two generally parallel conductor structures. Also included are a plurality of substantially vertically extending relatively low-k volumes sealed within the substantially horizontal layers and the substantially horizontally extending volumes between the at least two generally parallel conductor structures. The substantially vertically extending relatively low-k volumes and the substantially horizontally extending relatively low-k volumes reduce parasitic capacitance between the at least two generally parallel conductor structures as compared to an otherwise comparable microelectronic circuit not including the relatively low-k volumes.

    摘要: A method for manufacturing a circuit includes the step of providing a first wiring level comprising first wiring level conductors separated by a first wiring level dielectric material. A first dielectric layer with a plurality of interconnect openings and a plurality of gap openings is formed above the first wiring level. The interconnect openings and the gap openings are pinched off with a pinching dielectric material to form relatively low dielectric constant (low-k) volumes in the gap openings. Metallic conductors comprising second wiring level conductors and interconnects to the first wiring level conductors are formed at the interconnect openings while maintaining the relatively low-k volumes in the gap openings. The gap openings with the relatively low-k volumes reduce parasitic capacitance between adjacent conductor structures formed by the conductors and interconnects.
