In a chromonic, relatively flat molecules form linear aggregates. For aqueous solutions, the molecules have a flat core, such as a carbon ring system, with highly water-soluble side groups, such as a sulfonate or carboxyl. The molecules aggregate in linear stacks with the flat cores lying one on top of the other. The aggregates are continuously growing and shrinking. At low concentration, most of the molecules exist as isolated monomers. As the concentration increases, the average stack size begins to grow. At a sufficiently high concentration, the long stacks of molecules interfere with each other to form liquid crystals.

Spin-on antireflective coating for integration of patternable dielectric materials and interconnect structures
InactiveUS20090081418A1Reduce complexityReduce the number of layersPhotosensitive materialsDecorative surface effectsPhotoresistChromophore
The present invention provides a method of fabricating an interconnect structure in which a patternable low-k material replaces the need for utilizing a separate photoresist and a dielectric material. Specifically, this invention relates to a simplified method of fabricating single-damascene and dual-damascene low-k interconnect structures with at least one patternable low-k dielectric and at least one inorganic antireflective coating. In general terms, a method is provided that includes providing at least one patternable low-k material on a surface of an inorganic antireflective coating that is located atop a substrate. The inorganic ARC is liquid deposited and comprises a polymer that has at least one monomer unit comprising the formula M-R1 wherein M is at least one of Si, Ge, B, Sn, Fe, Ta, Ti, Ni, Hf and La and R1 is a chromophore. At least one interconnect pattern is formed within the at least one patternable low-k material and thereafter the at least one patternable low-k material is cured. The inventive method can be used to form dual-damascene interconnect structures as well as single-damascene interconnect structures.

Novel, developer soluble anti-reflective coating compositions and methods of using those compositions are provided. The compositions comprise a polymer and / or oligomer having acid functional groups and dissolved in a solvent system along with a cross linker, a photoacid generator, and optionally a chromophore. The preferred acid functional group is a carboxylic acid, while the preferred crosslinker is a vinyl ether crosslinker. In use, the compositions are applied to a substrate and thermally crosslinked. Upon exposure to light (and optionally a post exposure bake), the cured compositions will decrosslink, rendering them soluble in typical photoresist developing solutions (e.g., alkaline developers). In one embodiment, the compositions can be used to form ion implant areas in microelectronic substrates.

Alignment of lyotropic chromonic liquid crystals at surfaces as monolayers and multilayered stacks
InactiveUS20020168511A1Easy fashionLiquid crystal compositionsMaterial nanotechnologyIn planeLiquid crystalline
A broad class of lyotropic liquid crystals of a non-surfactant nature, the so-called lyotropic chromonic liquid crystals (LCLCs), are alignable with the techniques, in particular, LCLCs can be aligned at a surface as one monomolecular layer as a stack of monomolecular layers. The method for monolayer alignment is based on alternate layer-by-layer adsorption of polyions and dyes from aqueous solutions that have liquid crystalline structure. Using this method, one is able to stack alternate monolayers of dye and polyion while controlling the long-range in-plane orientation of the dye molecules within the plane of each layer. The feature of controlling the alignment of LCLCs enables one to create practical devices from them. For example, alignment of multilayered stacks allows one to use the resulting dried LCLC films in optical devices, for example, as internal polarizers, color filters, optical compensators, band-gap filters, and the like.
