  • Publication number: 20070133266
    Abstract: Structures and methods for operating the same. The structure includes (a) a substrate; (b) a first and second electrode regions on the substrate; and (c) a third electrode region disposed between the first and second electrode regions. In response to a first write voltage potential applied between the first and third electrode regions, the third electrode region changes its own shape, such that in response to a pre-specified read voltage potential subsequently applied between the first and third electrode regions, a sensing current flows between the first and third electrode regions. In addition, in response to a second write voltage potential being applied between the second and third electrode regions, the third electrode region changes its own shape such that in response to the pre-specified read voltage potential applied between the first and third electrode regions, said sensing current does not flow between the first and third electrode regions.

  • Publication number: 20070123028
    Abstract: Methods of forming low-k dielectric layers for use in the manufacture of semiconductor devices and fabricating semiconductor structures using the low-k dielectric material. 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.

  • Publication number: 20070099416
    Abstract: Sublithographic contact apertures through a dielectric are formed in a stack of dielectric, hardmask and oxide-containing seed layer. An initial aperture through the seed layer receives a deposition of oxide by liquid phase deposition, which adheres selectively to the exposed vertical walls of the aperture in the seed layer. The sublithographic aperture, reduced in size by the thickness of the added material, defines a reduced aperture in the hardmask. The reduced hardmask then defines the sublithographic aperture through the dielectric.

Then, the capping region is removed so as to expose the positioning region to the surrounding ambient. Then, the positioning region is removed so as to expose the memory region to the surrounding ambient. Then, the memory region is directionally etched with remaining portions of the conformal protection layer serving as a blocking mask.

  • Publication number: 20070059891
    Abstract: Disclosed herein is an imaging method for patterning component shapes (e.g., fins, gate electrodes, etc.) into a substrate. By conducting a trim step prior to performing either an additive or subtractive sidewall image transfer process, the method avoids the formation of a loop pattern in a hard mask and, thus, avoids a post-SIT process trim step requiring alignment of a trim mask to sub-lithographic features to form a hard mask pattern with the discrete segments. In one embodiment a hard mask is trimmed prior to conducting an additive SIT process so that a loop pattern is not formed. In another embodiment an oxide layer and memory layer that are used to form a mandrel are trimmed prior to the conducting a subtractive SIT process. A mask is then used to protect portions of the mandrel during etch back of the oxide layer so that a loop pattern is not formed.
