    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: A method of forming a doped gate structure on a semiconductor device and a semiconductor structure formed in that method are provided. The method comprises the steps of providing a semiconductor device including a gate dielectric layer, and forming a gate stack on said dielectric layer. This latter step, in turn, includes the steps of forming a first gate layer on the dielectric layer, and forming a second disposable layer on top of the first gate layer. A fat spacer is formed around the first gate layer and the second layers. The second disposable layer is removed, and ions are implanted in the first gate layer to supply additional dopant into the gate above the gate dielectric layer, while the fat disposable spacer keeps the implanted ions away from the critical source and drain diffusion region.
