  • Patent number: 10043703
    Abstract: A semiconductor cell includes a dielectric layer. An array of at least four parallel metal lines is disposed within the dielectric layer, the metal lines having line widths that are substantially equal to or greater than a predetermined minimum line width. Line spacers are disposed between the metal lines, the line spacers having line spacer widths that are substantially equal to or greater than a predetermined minimum line spacer width. An overall cell height of the cell is substantially equal to an integer multiple of a plurality of cell tracks, each cell track being a minimum pitch of the cell. The minimum pitch being defined by the minimum line width plus the minimum line spacer width. The minimum pitch is equal to or less than 36 nm. Not all of the line widths are substantially equal and every other line spacer width is substantially equal.

  • Publication number: 20090163672
    Abstract: Methods are described herein for converting carbocationically terminated polymers to anionically terminated polymers. These methods comprise: (a) providing a carbocationically terminated polymeric moiety; (b) reacting the carbocationically terminated polymeric moiety with a heterocyclic compound of the formula where —X— is selected from —S—, —O—, —NH— and —NR—, and where R is an alkyl group or an aryl group, thereby providing an end-capped polymeric moiety; and (c) reacting the end-capped polymeric moiety with an organolithium compound to yield an anionically terminated polymeric moiety. Also described are block copolymers in which a first polymer block comprising cationically polymerized monomers is linked to a second polymer block comprising anionically polymerized monomers by a group, as well as a polymer in which a polymer block comprising cationically polymerized monomers is linked to a halogenated silane residue or a carbosilane residue by a group.

  • Patent number: 7547472
    Abstract: A new, non-wrapping approach to functionalizing nanotubes, such as carbon nanotubes, in organic and inorganic solvents is provided. In accordance with certain embodiments, carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups. Various embodiments provide polymers that noncovalently bond with carbon nanotubes in a non-wrapping fashion. For example, various embodiments of polymers are provided that comprise a relatively rigid backbone that is suitable for noncovalently bonding with a carbon nanotube substantially along the nanotube's length, as opposed to about its diameter. In preferred polymers, the major interaction between the polymer backbone and the nanotube surface is parallel ?-stacking. In certain implementations, the polymers further comprise at least one functional extension from the backbone that are any of various desired functional groups for functionalizing a carbon nanotube.
