摘要： Design structure embodied in a machine readable medium for designing, manufacturing, or testing a design in which the design structure includes shallow trench isolation filled with liquid phase deposited silicon dioxide (LPD-SiO2). The shallow trench isolation region is used to isolate two active regions formed on a silicon-on-insulator (SOI) substrate. By selectively depositing the oxide so that the active areas are not covered with the oxide, the polishing needed to planarize the wafer is significantly reduced as compared to a chemical-vapor deposited oxide layer that covers the entire wafer surface. Additionally, the LPD-SiO2 does not include the growth seams that CVD silicon dioxide does. Accordingly, the etch rate of the LPD-SiO2 is uniform across its entire expanse thereby preventing cavities and other etching irregularities present in prior art shallow trench isolation regions in which the etch rate of growth seams exceeds that of the other oxide areas.

摘要： A dielectric in an integrated circuit is formed by creating oriented cylindrical voids in a conventional dielectric material. Preferably, voids are formed by first forming multiple relatively long, thin carbon nanotubes perpendicular to a surface of an integrated circuit wafer, depositing a conventional dielectric on the surface surrounding the carbon nanotubes, and then removing the carbon nanotubes to produce the voids. A layer of dielectric and voids thus formed can be patterned or otherwise processed using any of various conventional processes. Recesses formed in the dielectric for conductors are lined with a non-conformal dielectric film to seal the voids. The use of a conventional dielectric material having numerous air voids substantially reduces the dielectric constant, leaving a dielectric structure which is both structurally strong and can be constructed compatibly with conventional processes and materials.

摘要： A conductive layer in an integrated circuit is formed as a sandwich having multiple sublayers, including at least one sublayer of oriented carbon nanotubes. The conductive layer sandwich preferably contains two sublayers of carbon nanotubes, in which the carbon nanotube orientation in one sublayer is substantially perpendicular to that of the other layer. The conductive layer sandwich preferably contains one or more additional sublayers of a conductive material, such as a metal. In one embodiment, oriented carbon nanotubes are created by forming a series of parallel surface ridges, covering the top and one side of the ridges with a catalyst inhibitor, and growing carbon nanotubes horizontally from the uncovered vertical sides of the ridges. In another embodiment, oriented carbon nanotubes are grown on the surface of a conductive material in the presence of a directional flow of reactant gases and a catalyst.

摘要： A dielectric in an integrated circuit is formed by creating oriented cylindrical voids in a conventional dielectric material. Preferably, voids are formed by first forming multiple relatively long, thin carbon nanotubes perpendicular to a surface of an integrated circuit wafer, by depositing a conventional dielectric on the surface to fill the area between the carbon nanotubes, and by then removing the carbon nanotubes to produce voids in place of the carbon nanotubes. A layer of dielectric and voids thus formed can be patterned or otherwise processed using any of various conventional processes. The use of a conventional dielectric material having numerous air voids substantially reduces the dielectric constant, leaving a dielectric structure which is both structurally strong and can be constructed compatibly with conventional processes and materials.

摘要： An integrated circuit and method for fabrication includes first and second structures, each including a set of sub-lithographic lines, and contact landing segments connected to at least one of the sub-lithographic lines at an end portion. The first and second structures are nested such that the sub-lithographic lines are disposed in a parallel manner within a width, and the contact landing segments of the first structure are disposed on an opposite side of a length of the sub-lithographic lines relative to the contact landing segments of the second structure. The contact landing segments for the first and second structures are included within the width dimension, wherein the width includes a dimension four times a minimum feature size achievable by lithography.

摘要： Conductive sidewall spacer structures are formed using a method that patterns structures (mandrels) and activates the sidewalls of the structures. Metal ions are attached to the sidewalls of the structures and these metal ions are reduced to form seed material. The structures are then trimmed and the seed material is plated to form wiring on the sidewalls of the structures.

摘要： A low-k dielectric material for use in the manufacture of semiconductor devices, semiconductor structures using the low-k dielectric material, and methods of forming such dielectric materials and fabricating such structures. The low-k dielectric material comprises carbon nanostructures, like carbon nanotubes or carbon buckyballs, that are characterized by an insulating electronic state. The carbon nanostructures may be converted to the insulating electronic state either before or after a layer containing the carbon nanostructures is formed on a substrate. One approach for converting the carbon nanostructures to the insulating electronic state is fluorination.

摘要： A combined wide-image and loop-cutter pattern is provided for both cutting and forming a wide-image section to a hard mask on a substrate formed by sidewall imaging techniques in a reduced number of photolithographic steps. A single mask is formed which provides a wide mask section while additionally providing a mask to protect the critical edges of an underlying hard mask during hard mask etching. After the hard mask is cut into sections, the protective portions of the follow-on mask are removed to expose the critical edges of the underlying hard mask while maintaining shapes necessary for defining wide-image sections. Thus, the hard mask cutting, hard mask critical edge protecting, and large area mask may be formed in a reduced number of steps.
